This represents the mass deletion of the of the tokenring support.
It gets rid of:
- the net/tr.c which the drivers depended on
- the drivers/net component
- the Kbuild infrastructure around it
- any tokenring related CONFIG_ settings in any defconfigs
- the tokenring headers in the include/linux dir
- the firmware associated with the tokenring drivers.
- any associated token ring documentation.

-Release 0.9.0 - Release
- Jul 17th 2000 Mike Phillips
-
- 1.2.0 - Final
- Feb 17th 2002 Mike Phillips
- Updated for submission to the 2.4.x kernel.
-
-Thanks:
- Terry Murphy from 3Com for tech docs and support,
- Adam D. Ligas for testing the driver.
-
-Note:
- This driver will NOT work with the 3C339 Token Ring cards, you need
-to use the tms380 driver instead.
-
-Options:
-
-The driver accepts three options: ringspeed, pkt_buf_sz and message_level.
-
-These options can be specified differently for each card found.
-
-ringspeed: Has one of three settings 0 (default), 4 or 16. 0 will
-make the card autosense the ringspeed and join at the appropriate speed,
-this will be the default option for most people. 4 or 16 allow you to
-explicitly force the card to operate at a certain speed. The card will fail
-if you try to insert it at the wrong speed. (Although some hubs will allow
-this so be *very* careful). The main purpose for explicitly setting the ring
-speed is for when the card is first on the ring. In autosense mode, if the card
-cannot detect any active monitors on the ring it will open at the same speed as
-its last opening. This can be hazardous if this speed does not match the speed
-you want the ring to operate at.
-
-pkt_buf_sz: This is this initial receive buffer allocation size. This will
-default to 4096 if no value is entered. You may increase performance of the
-driver by setting this to a value larger than the network packet size, although
-the driver now re-sizes buffers based on MTU settings as well.
-
-message_level: Controls level of messages created by the driver. Defaults to 0:
-which only displays start-up and critical messages. Presently any non-zero
-value will display all soft messages as well. NB This does not turn
-debugging messages on, that must be done by modified the source code.
-
-Variable MTU size:
-
-The driver can handle a MTU size up to either 4500 or 18000 depending upon
-ring speed. The driver also changes the size of the receive buffers as part
-of the mtu re-sizing, so if you set mtu = 18000, you will need to be able
-to allocate 16 * (sk_buff with 18000 buffer size) call it 18500 bytes per ring
-position = 296,000 bytes of memory space, plus of course anything
-necessary for the tx sk_buff's. Remember this is per card, so if you are
-building routers, gateway's etc, you could start to use a lot of memory
-real fast.

-Release 0.2.0 - Release
- June 8th 1999 Peter De Schrijver & Mike Phillips
-Release 0.9.C - Release
- April 18th 2001 Mike Phillips
-
-Thanks:
-Erik De Cock, Adrian Bridgett and Frank Fiene for their
-patience and testing.
-Donald Champion for the cardbus support
-Kyle Lucke for the dma api changes.
-Jonathon Bitner for hardware support.
-Everybody on linux-tr for their continued support.
-
-Options:
-
-The driver accepts four options: ringspeed, pkt_buf_sz,
-message_level and network_monitor.
-
-These options can be specified differently for each card found.
-
-ringspeed: Has one of three settings 0 (default), 4 or 16. 0 will
-make the card autosense the ringspeed and join at the appropriate speed,
-this will be the default option for most people. 4 or 16 allow you to
-explicitly force the card to operate at a certain speed. The card will fail
-if you try to insert it at the wrong speed. (Although some hubs will allow
-this so be *very* careful). The main purpose for explicitly setting the ring
-speed is for when the card is first on the ring. In autosense mode, if the card
-cannot detect any active monitors on the ring it will not open, so you must
-re-init the card at the appropriate speed. Unfortunately at present the only
-way of doing this is rmmod and insmod which is a bit tough if it is compiled
-in the kernel.
-
-pkt_buf_sz: This is this initial receive buffer allocation size. This will
-default to 4096 if no value is entered. You may increase performance of the
-driver by setting this to a value larger than the network packet size, although
-the driver now re-sizes buffers based on MTU settings as well.
-
-message_level: Controls level of messages created by the driver. Defaults to 0:
-which only displays start-up and critical messages. Presently any non-zero
-value will display all soft messages as well. NB This does not turn
-debugging messages on, that must be done by modified the source code.
-
-network_monitor: Any non-zero value will provide a quasi network monitoring
-mode. All unexpected MAC frames (beaconing etc.) will be received
-by the driver and the source and destination addresses printed.
-Also an entry will be added in /proc/net called olympic_tr%d, where tr%d
-is the registered device name, i.e tr0, tr1, etc. This displays low
-level information about the configuration of the ring and the adapter.
-This feature has been designed for network administrators to assist in
-the diagnosis of network / ring problems. (This used to OLYMPIC_NETWORK_MONITOR,
-but has now changed to allow each adapter to be configured differently and
-to alleviate the necessity to re-compile olympic to turn the option on).
-
-Multi-card:
-
-The driver will detect multiple cards and will work with shared interrupts,
-each card is assigned the next token ring device, i.e. tr0 , tr1, tr2. The
-driver should also happily reside in the system with other drivers. It has
-been tested with ibmtr.c running, and I personally have had one Olicom PCI
-card and two IBM olympic cards (all on the same interrupt), all running
-together.
-
-Variable MTU size:
-
-The driver can handle a MTU size up to either 4500 or 18000 depending upon
-ring speed. The driver also changes the size of the receive buffers as part
-of the mtu re-sizing, so if you set mtu = 18000, you will need to be able
-to allocate 16 * (sk_buff with 18000 buffer size) call it 18500 bytes per ring
-position = 296,000 bytes of memory space, plus of course anything
-necessary for the tx sk_buff's. Remember this is per card, so if you are
-building routers, gateway's etc, you could start to use a lot of memory
-real fast.

-Text File for the SMC TokenCard TokenRing Linux driver (smctr.c).
- By Jay Schulist <jschlst@samba.org>
-
-The Linux SMC Token Ring driver works with the SMC TokenCard Elite (8115T)
-ISA and SMC TokenCard Elite/A (8115T/A) MCA adapters.
-
-Latest information on this driver can be obtained on the Linux-SNA WWW site.
-Please point your browser to: http://www.linux-sna.org
-
-This driver is rather simple to use. Select Y to Token Ring adapter support
-in the kernel configuration. A choice for SMC Token Ring adapters will
-appear. This drives supports all SMC ISA/MCA adapters. Choose this
-option. I personally recommend compiling the driver as a module (M), but if you
-you would like to compile it statically answer Y instead.
-
-This driver supports multiple adapters without the need to load multiple copies
-of the driver. You should be able to load up to 7 adapters without any kernel
-modifications, if you are in need of more please contact the maintainer of this
-driver.
-
-Load the driver either by lilo/loadlin or as a module. When a module using the
-following command will suffice for most:
-
-# modprobe smctr
-smctr.c: v1.00 12/6/99 by jschlst@samba.org
-tr0: SMC TokenCard 8115T at Io 0x300, Irq 10, Rom 0xd8000, Ram 0xcc000.
-
-Now just setup the device via ifconfig and set and routes you may have. After
-this you are ready to start sending some tokens.
-
-Errata:
-1). For anyone wondering where to pick up the SMC adapters please browse
- to http://www.smc.com
-
-2). If you are the first/only Token Ring Client on a Token Ring LAN, please
- specify the ringspeed with the ringspeed=[4/16] module option. If no
- ringspeed is specified the driver will attempt to autodetect the ring
- speed and/or if the adapter is the first/only station on the ring take
- the appropriate actions.
-
- NOTE: Default ring speed is 16MB UTP.
-
-3). PnP support for this adapter sucks. I recommend hard setting the
- IO/MEM/IRQ by the jumpers on the adapter. If this is not possible
- load the module with the following io=[ioaddr] mem=[mem_addr]
- irq=[irq_num].
-
- The following IRQ, IO, and MEM settings are supported.
-
- IO ports:
- 0x200, 0x220, 0x240, 0x260, 0x280, 0x2A0, 0x2C0, 0x2E0, 0x300,
- 0x320, 0x340, 0x360, 0x380.
-
- IRQs:
- 2, 3, 4, 5, 7, 8, 9, 10, 11, 12, 13, 14, 15
-
- Memory addresses:
- 0xA0000, 0xA4000, 0xA8000, 0xAC000, 0xB0000, 0xB4000,

-Text file for the Linux SysKonnect Token Ring ISA/PCI Adapter Driver.
- Text file by: Jay Schulist <jschlst@samba.org>
-
-The Linux SysKonnect Token Ring driver works with the SysKonnect TR4/16(+) ISA,
-SysKonnect TR4/16(+) PCI, SysKonnect TR4/16 PCI, and older revisions of the
-SK NET TR4/16 ISA card.
-
-Latest information on this driver can be obtained on the Linux-SNA WWW site.
-Please point your browser to:
-http://www.linux-sna.org
-
-Many thanks to Christoph Goos for his excellent work on this driver and
-SysKonnect for donating the adapters to Linux-SNA for the testing and
-maintenance of this device driver.
-
-Important information to be noted:
-1. Adapters can be slow to open (~20 secs) and close (~5 secs), please be
- patient.
-2. This driver works very well when autoprobing for adapters. Why even
- think about those nasty io/int/dma settings of modprobe when the driver
- will do it all for you!
-
-This driver is rather simple to use. Select Y to Token Ring adapter support
-in the kernel configuration. A choice for SysKonnect Token Ring adapters will
-appear. This drives supports all SysKonnect ISA and PCI adapters. Choose this
-option. I personally recommend compiling the driver as a module (M), but if you
-you would like to compile it statically answer Y instead.
-
-This driver supports multiple adapters without the need to load multiple copies
-of the driver. You should be able to load up to 7 adapters without any kernel
-modifications, if you are in need of more please contact the maintainer of this
-driver.
-
-Load the driver either by lilo/loadlin or as a module. When a module using the
-following command will suffice for most:
-
-# modprobe sktr
-
-This will produce output similar to the following: (Output is user specific)
-
-sktr.c: v1.01 08/29/97 by Christoph Goos
-tr0: SK NET TR 4/16 PCI found at 0x6100, using IRQ 17.
-tr1: SK NET TR 4/16 PCI found at 0x6200, using IRQ 16.
-tr2: SK NET TR 4/16 ISA found at 0xa20, using IRQ 10 and DMA 5.

- * There are two ways of implementing rx on the 359 NIC, either

- * The Rx works with a ring of Rx descriptors. At initialise time the ring
- * entries point to the next entry except for the last entry in the ring
- * which points to 0. The card is programmed with the location of the first
- * available descriptor and keeps reading the next_ptr until next_ptr is set
- * to 0. Hopefully with a ring size of 16 the card will never get to read a next_ptr
- * of 0. As the Rx interrupt is received we copy the frame up to the protocol layers
- * and then point the end of the ring to our current position and point our current
- * position to 0, therefore making the current position the last position on the ring.
- * The last position on the ring therefore loops continually loops around the rx ring.
- *
- * rx_ring_tail is the position on the ring to process next. (Think of a snake, the head
- * expands as the card adds new packets and we go around eating the tail processing the
- * packets.)
- *
- * Undoubtably it could be streamlined and improved upon, but at the moment it works
- * and the fast path through the routine is fine.
- *
- * adv_rx_ring could be inlined to increase performance, but its called a *lot* of times

-/* ibmtr.c: A shared-memory IBM Token Ring 16/4 driver for linux
- *
- * Written 1993 by Mark Swanson and Peter De Schrijver.
- * This software may be used and distributed according to the terms
- * of the GNU General Public License, incorporated herein by reference.
- *
- * This device driver should work with Any IBM Token Ring Card that does
- * not use DMA.
- *
- * I used Donald Becker's (becker@scyld.com) device driver work
- * as a base for most of my initial work.
- *
- * Changes by Peter De Schrijver
- * (Peter.Deschrijver@linux.cc.kuleuven.ac.be) :
- *
- * + changed name to ibmtr.c in anticipation of other tr boards.
- * + changed reset code and adapter open code.
- * + added SAP open code.
- * + a first attempt to write interrupt, transmit and receive routines.
- *
- * Changes by David W. Morris (dwm@shell.portal.com) :
- * 941003 dwm: - Restructure tok_probe for multiple adapters, devices.
- * + Add comments, misc reorg for clarity.
- * + Flatten interrupt handler levels.
- *
- * Changes by Farzad Farid (farzy@zen.via.ecp.fr)
- * and Pascal Andre (andre@chimay.via.ecp.fr) (March 9 1995) :
- * + multi ring support clean up.
- * + RFC1042 compliance enhanced.
- *
- * Changes by Pascal Andre (andre@chimay.via.ecp.fr) (September 7 1995) :
- * + bug correction in tr_tx
- * + removed redundant information display
- * + some code reworking
- *
- * Changes by Michel Lespinasse (walken@via.ecp.fr),
- * Yann Doussot (doussot@via.ecp.fr) and Pascal Andre (andre@via.ecp.fr)
- * (February 18, 1996) :
- * + modified shared memory and mmio access port the driver to
- * alpha platform (structure access -> readb/writeb)
- *
- * Changes by Steve Kipisz (bungy@ibm.net or kipisz@vnet.ibm.com)
- * (January 18 1996):
- * + swapped WWOR and WWCR in ibmtr.h
- * + moved some init code from tok_probe into trdev_init. The
- * PCMCIA code can call trdev_init to complete initializing
- * the driver.
- * + added -DPCMCIA to support PCMCIA
- * + detecting PCMCIA Card Removal in interrupt handler. If
- * ISRP is FF, then a PCMCIA card has been removed
- * 10/2000 Burt needed a new method to avoid crashing the OS
- *
- * Changes by Paul Norton (pnorton@cts.com) :
- * + restructured the READ.LOG logic to prevent the transmit SRB
- * from being rudely overwritten before the transmit cycle is
- * complete. (August 15 1996)
- * + completed multiple adapter support. (November 20 1996)
- * + implemented csum_partial_copy in tr_rx and increased receive
- * buffer size and count. Minor fixes. (March 15, 1997)
- *
- * Changes by Christopher Turcksin <wabbit@rtfc.demon.co.uk>
- * + Now compiles ok as a module again.
- *
- * Changes by Paul Norton (pnorton@ieee.org) :
- * + moved the header manipulation code in tr_tx and tr_rx to
- * net/802/tr.c. (July 12 1997)
- * + add retry and timeout on open if cable disconnected. (May 5 1998)
- * + lifted 2000 byte mtu limit. now depends on shared-RAM size.
- * May 25 1998)
- * + can't allocate 2k recv buff at 8k shared-RAM. (20 October 1998)
- *
- * Changes by Joel Sloan (jjs@c-me.com) :
- * + disable verbose debug messages by default - to enable verbose
- * debugging, edit the IBMTR_DEBUG_MESSAGES define below
- *
- * Changes by Mike Phillips <phillim@amtrak.com> :
- * + Added extra #ifdef's to work with new PCMCIA Token Ring Code.
- * The PCMCIA code now just sets up the card so it can be recognized
- * by ibmtr_probe. Also checks allocated memory vs. on-board memory
- * for correct figure to use.
- *
- * Changes by Tim Hockin (thockin@isunix.it.ilstu.edu) :
- * + added spinlocks for SMP sanity (10 March 1999)
- *
- * Changes by Jochen Friedrich to enable RFC1469 Option 2 multicasting
- * i.e. using functional address C0 00 00 04 00 00 to transmit and
- * receive multicast packets.
- *
- * Changes by Mike Sullivan (based on original sram patch by Dave Grothe
- * to support windowing into on adapter shared ram.
- * i.e. Use LANAID to setup a PnP configuration with 16K RAM. Paging
- * will shift this 16K window over the entire available shared RAM.
- *
- * Changes by Peter De Schrijver (p2@mind.be) :
- * + fixed a problem with PCMCIA card removal
- *
- * Change by Mike Sullivan et al.:
- * + added turbo card support. No need to use lanaid to configure
- * the adapter into isa compatibility mode.
- *
- * Changes by Burt Silverman to allow the computer to behave nicely when
- * a cable is pulled or not in place, or a PCMCIA card is removed hot.

-/*======================================================================
-
- A PCMCIA token-ring driver for IBM-based cards
-
- This driver supports the IBM PCMCIA Token-Ring Card.
- Written by Steve Kipisz, kipisz@vnet.ibm.com or
- bungy@ibm.net
-
- Written 1995,1996.
-
- This code is based on pcnet_cs.c from David Hinds.
-
- V2.2.0 February 1999 - Mike Phillips phillim@amtrak.com
-
- Linux V2.2.x presented significant changes to the underlying
- ibmtr.c code. Mainly the code became a lot more organized and
- modular.
-
- This caused the old PCMCIA Token Ring driver to give up and go
- home early. Instead of just patching the old code to make it
- work, the PCMCIA code has been streamlined, updated and possibly
- improved.
-
- This code now only contains code required for the Card Services.
- All we do here is set the card up enough so that the real ibmtr.c
- driver can find it and work with it properly.
-
- i.e. We set up the io port, irq, mmio memory and shared ram
- memory. This enables ibmtr_probe in ibmtr.c to find the card and
- configure it as though it was a normal ISA and/or PnP card.
-
- CHANGES
-
- v2.2.5 April 1999 Mike Phillips (phillim@amtrak.com)
- Obscure bug fix, required changed to ibmtr.c not ibmtr_cs.c
-
- v2.2.7 May 1999 Mike Phillips (phillim@amtrak.com)
- Updated to version 2.2.7 to match the first version of the kernel
- that the modification to ibmtr.c were incorporated into.
-
- v2.2.17 July 2000 Burt Silverman (burts@us.ibm.com)
- Address translation feature of PCMCIA controller is usable so
- memory windows can be placed in High memory (meaning above
- 0xFFFFF.)

- * 12/10/99 - Alpha Release 0.1.0
- * First release to the public
- * 03/03/00 - Merged to kernel, indented -kr -i8 -bri0, fixed some missing
- * malloc free checks, reviewed code. <alan@redhat.com>
- * 03/13/00 - Added spinlocks for smp
- * 03/08/01 - Added support for module_init() and module_exit()
- * 08/15/01 - Added ioctl() functionality for debugging, changed netif_*_queue
- * calls and other incorrectness - Kent Yoder <yoder1@us.ibm.com>
- * 11/05/01 - Restructured the interrupt function, added delays, reduced the
- * the number of TX descriptors to 1, which together can prevent
- * the card from locking up the box - <yoder1@us.ibm.com>
- * 09/27/02 - New PCI interface + bug fix. - <yoder1@us.ibm.com>
- * 11/13/02 - Removed free_irq calls which could cause a hang, added
- * netif_carrier_{on|off} - <yoder1@us.ibm.com>
- *
- * To Do:
- *
- *
- * If Problems do Occur
- * Most problems can be rectified by either closing and opening the interface
- * (ifconfig down and up) or rmmod and insmod'ing the driver (a bit difficult
- * if compiled into the kernel).

- * Handle interrupts generated by the card
- *
- * The MicroChannel Madge cards need slightly more handling
- * after an interrupt than other TMS380 cards do.
- *
- * First we must make sure it was this card that generated the
- * interrupt (since interrupt sharing is allowed). Then,
- * because we're using level-triggered interrupts (as is
- * standard on MCA), we must toggle the interrupt line
- * on the card in order to claim and acknowledge the interrupt.
- * Once that is done, the interrupt should be handlable in
- * the normal tms380tr_interrupt() routine.
- *
- * There's two ways we can check to see if the interrupt is ours,
- * both with their own disadvantages...
- *
- * 1) Read in the SIFSTS register from the TMS controller. This
- * is guaranteed to be accurate, however, there's a fairly
- * large performance penalty for doing so: the Madge chips
- * must request the register from the Eagle, the Eagle must
- * read them from its internal bus, and then take the route
- * back out again, for a 16bit read.
- *
- * 2) Use the MC_CONTROL_REG0_SINTR bit from the Madge ASICs.
- * The major disadvantage here is that the accuracy of the
- * bit is in question. However, it cuts out the extra read
- * cycles it takes to read the Eagle's SIF, as its only an
- * 8bit read, and theoretically the Madge bit is directly
- * connected to the interrupt latch coming out of the Eagle
- * hardware (that statement is not verified).
- *
- * I can't determine which of these methods has the best win. For now,
- * we make a compromise. Use the Madge way for the first interrupt,
- * which should be the fast-path, and then once we hit the first
- * interrupt, keep on trying using the SIF method until we've
- * exhausted all contiguous interrupts.

- *
- * Linux driver for IBM PCI tokenring cards based on the Pit/Pit-Phy/Olympic
- * chipset.
- *
- * Base Driver Skeleton:
- * Written 1993-94 by Donald Becker.
- *
- * Copyright 1993 United States Government as represented by the
- * Director, National Security Agency.
- *
- * Thanks to Erik De Cock, Adrian Bridgett and Frank Fiene for their
- * assistance and perserverance with the testing of this driver.
- *
- * This software may be used and distributed according to the terms
- * of the GNU General Public License, incorporated herein by reference.
- *
- * 4/27/99 - Alpha Release 0.1.0
- * First release to the public
- *
- * 6/8/99 - Official Release 0.2.0
- * Merged into the kernel code
- * 8/18/99 - Updated driver for 2.3.13 kernel to use new pci
- * resource. Driver also reports the card name returned by
- * the pci resource.
- * 1/11/00 - Added spinlocks for smp
- * 2/23/00 - Updated to dev_kfree_irq
- * 3/10/00 - Fixed FDX enable which triggered other bugs also
- * squashed.
- * 5/20/00 - Changes to handle Olympic on LinuxPPC. Endian changes.
- * The odd thing about the changes is that the fix for
- * endian issues with the big-endian data in the arb, asb...
- * was to always swab() the bytes, no matter what CPU.
- * That's because the read[wl]() functions always swap the
- * bytes on the way in on PPC.
- * Fixing the hardware descriptors was another matter,
- * because they weren't going through read[wl](), there all
- * the results had to be in memory in le32 values. kdaaker
- *
- * 12/23/00 - Added minimal Cardbus support (Thanks Donald).
- *
- * 03/09/01 - Add new pci api, dev_base_lock, general clean up.
- *
- * 03/27/01 - Add new dma pci (Thanks to Kyle Lucke) and alloc_trdev
- * Change proc_fs behaviour, now one entry per adapter.
- *
- * 04/09/01 - Couple of bug fixes to the dma unmaps and ejecting the
- * adapter when live does not take the system down with it.
- *
- * 06/02/01 - Clean up, copy skb for small packets
- *
- * 06/22/01 - Add EISR error handling routines
- *
- * 07/19/01 - Improve bad LAA reporting, strip out freemem
- * into a separate function, its called from 3
- * different places now.
- * 02/09/02 - Replaced sleep_on.
- * 03/01/02 - Replace access to several registers from 32 bit to
- * 16 bit. Fixes alignment errors on PPC 64 bit machines.
- * Thanks to Al Trautman for this one.
- * 03/10/02 - Fix BUG in arb_cmd. Bug was there all along but was
- * silently ignored until the error checking code
- * went into version 1.0.0
- * 06/04/02 - Add correct start up sequence for the cardbus adapters.
- * Required for strict compliance with pci power mgmt specs.
- * To Do:
- *
- * Wake on lan
- *
- * If Problems do Occur
- * Most problems can be rectified by either closing and opening the interface
- * (ifconfig down and up) or rmmod and insmod'ing the driver (a bit difficult
- * if compiled into the kernel).

- * tms380tr.c: A network driver library for Texas Instruments TMS380-based
- * Token Ring Adapters.
- *
- * Originally sktr.c: Written 1997 by Christoph Goos
- *
- * A fine result of the Linux Systems Network Architecture Project.
- * http://www.vanheusden.com/sna/
- *
- * This software may be used and distributed according to the terms
- * of the GNU General Public License, incorporated herein by reference.
- *
- * The following modules are currently available for card support:
- * - tmspci (Generic PCI card support)
- * - abyss (Madge PCI support)
- * - tmsisa (SysKonnect TR4/16 ISA)
- *
- * Sources:
- * - The hardware related parts of this driver are take from
- * the SysKonnect Token Ring driver for Windows NT.
- * - I used the IBM Token Ring driver 'ibmtr.c' as a base for this
- * driver, as well as the 'skeleton.c' driver by Donald Becker.
- * - Also various other drivers in the linux source tree were taken
- * as samples for some tasks.
- * - TI TMS380 Second-Generation Token Ring User's Guide
- * - TI datasheets for respective chips
- * - David Hein at Texas Instruments
- * - Various Madge employees
- *
- * Maintainer(s):
- * JS Jay Schulist jschlst@samba.org
- * CG Christoph Goos cgoos@syskonnect.de
- * AF Adam Fritzler
- * MLP Mike Phillips phillim@amtrak.com
- * JF Jochen Friedrich jochen@scram.de
- *
- * Modification History:
- * 29-Aug-97 CG Created
- * 04-Apr-98 CG Fixed problems caused by tok_timer_check
- * 10-Apr-98 CG Fixed lockups at cable disconnection
- * 27-May-98 JS Formated to Linux Kernel Format
- * 31-May-98 JS Hacked in PCI support
- * 16-Jun-98 JS Modulized for multiple cards with one driver
- * Sep-99 AF Renamed to tms380tr (supports more than SK's)
- * 23-Sep-99 AF Added Compaq and Thomas-Conrad PCI support
- * Fixed a bug causing double copies on PCI
- * Fixed for new multicast stuff (2.2/2.3)
- * 25-Sep-99 AF Uped TPL_NUM from 3 to 9
- * Removed extraneous 'No free TPL'
- * 22-Dec-99 AF Added Madge PCI Mk2 support and generalized
- * parts of the initilization procedure.
- * 30-Dec-99 AF Turned tms380tr into a library ala 8390.
- * Madge support is provided in the abyss module
- * Generic PCI support is in the tmspci module.
- * 30-Nov-00 JF Updated PCI code to support IO MMU via
- * pci_map_static(). Alpha uses this MMU for ISA
- * as well.
- * 14-Jan-01 JF Fix DMA on ifdown/ifup sequences. Some
- * cleanup.
- * 13-Jan-02 JF Add spinlock to fix race condition.
- * 09-Nov-02 JF Fixed printks to not SPAM the console during
- * normal operation.
- * 30-Dec-02 JF Removed incorrect __init from
- * tms380tr_init_card.
- * 22-Jul-05 JF Converted to dma-mapping.
- *
- * To do:
- * 1. Multi/Broadcast packet handling (this may have fixed itself)
- * 2. Write a sktrisa module that includes the old ISA support (done)
- * 3. Allow modules to load their own microcode
- * 4. Speed up the BUD process -- freezing the kernel for 3+sec is
- * quite unacceptable.
- * 5. Still a few remaining stalls when the cable is unplugged.
