netdev_* macros directly, feedback from previous patch.
2) Changed soft commands to avoid crash when running
in interrupt context.
3) Fixed link status not reflecting correct status when NetworkManager
is running. Added MODULE_FIRMWARE declarations.
Following were the previous patches.
Patch V7:
1) Minor comments from v6 release regarding debug statements.

2) Consolidated some receive processing routines.
3) Removed link status polling method.
https://patchwork.ozlabs.org/patch/459514/
Patch V5:
Based on the feedback from earlier patches with regards to
consolidation of common functions like device init, register
programming for cn66xx and cn68xx devices.
https://patchwork.ozlabs.org/patch/438979/
Patch V4:
Following were the changes based on the feedback from earlier patch:
1) Added mmiowb while synchronizing queue updates and other hw
interactions.
2) Statistics will now be incremented non-atomically per each ring.
liquidio_get_stats will add stats of each ring while reporting the
total statistics counts.
3) Modified liquidio_ioctl to return proper return codes.
4) Modified device naming to use standard Ethernet naming.
5) Global function names in the driver will have lio_/liquidio_/octeon_
prefix.
6) Ethtool related changes for:
Removed redundant stats and jiffies.
Use default ethtool handler of link status.
Speed setting will make use of ethtool_cmd_speed_set.
7) Added checks for pci_map_* return codes.
8) Check for signals while waiting in interruptible mode

Link failures have been observed when using the KSZ9031 with HP 1810-8G
and HP 1910-8G network switches. Center the FLP timing at 16ms to help
avoid intermittent link failures.
>From the KSZ9031RNX and KSZ9031MNX data sheets revision 2.2, section
"Auto-Negotiation Timing":
The KSZ9031[RNX or MNX] Fast Link Pulse (FLP) burst-to-burst
transmit timing for Auto-Negotiation defaults to 8ms. IEEE 802.3
Standard specifies this timing to be 16ms +/-8ms. Some PHY link
partners need to receive the FLP with 16ms centered timing;
otherwise, there can be intermittent link failures and long
link-up times.
The PHY data sheet recommends configuring the FLP burst registers after
power-up/reset and immediately thereafter restarting auto-negotiation, so
we center the FLP timing at 16ms and then restart auto-negotiation in the
config_init for KSZ9031.

net: bcmgenet: improve TX timeout
Dump useful ring statistics along with interrupt status, software
maintained pointers and hardware registers to help troubleshoot TX queue
stalls.
When a timeout occurs, disable TX NAPI for the rings, dump their states
while interrupts are disabled, re-enable interrupts, NAPI and queue flow
control to help with the recovery.

batman-adv: Add required includes to all files
The header files could not be build indepdent from each other. This is
happened because headers didn't include the files for things they've used.
This was problematic because the success of a build depended on the
knowledge about the right order of local includes.
Also source files were not including everything they've used explicitly.
Instead they required that transitive includes are always stable. This is
problematic because some transitive includes are not obvious, depend on
config settings and may not be stable in the future.
The order for include blocks are:
* primary headers (main.h and the *.h file of a *.c file)
* global linux headers
* required local headers
* extra forward declarations for pointers in function/struct declarations
The only exceptions are linux/bitops.h and linux/if_ether.h in packet.h.
This header file is shared with userspace applications like batctl and must
therefore build together with userspace applications. The header
linux/bitops.h is not part of the uapi headers and linux/if_ether.h
conflicts with the musl implementation of netinet/if_ether.h. The
maintainers rejected the use of __KERNEL__ preprocessor checks and thus
these two headers are only in main.h. All files using packet.h first have
to include main.h to work correctly.

eBPF programs attached to ingress and egress qdiscs see inconsistent skb->data.
For ingress L2 header is already pulled, whereas for egress it's present.

Since programs don't change skb internal pointers it is safe to do

later pt->func() will not be affected.
Multiple taps via packet_rcv(), tpacket_rcv() are doing the same trick

inet: add IP_BIND_ADDRESS_NO_PORT to overcome bind(0) limitations
When an application needs to force a source IP on an active TCP socket
it has to use bind(IP, port=x).
As most applications do not want to deal with already used ports, x is
often set to 0, meaning the kernel is in charge to find an available
port.
But kernel does not know yet if this socket is going to be a listener or
be connected.
It has very limited choices (no full knowledge of final 4-tuple for a
connect())
With limited ephemeral port range (about 32K ports), it is very easy to
fill the space.
This patch adds a new SOL_IP socket option, asking kernel to ignore
the 0 port provided by application in bind(IP, port=0) and only
remember the given IP address.
The port will be automatically chosen at connect() time, in a way
that allows sharing a source port as long as the 4-tuples are unique.
This new feature is available for both IPv4 and IPv6 (Thanks Neal)
Tested:
Wrote a test program and checked its behavior on IPv4 and IPv6.
strace(1) shows sequences of bind(IP=127.0.0.2, port=0) followed by
connect().
Also getsockname() show that the port is still 0 right after bind()
but properly allocated after connect().
socket(PF_INET, SOCK_STREAM, IPPROTO_IP) = 5
setsockopt(5, SOL_IP, IP_BIND_ADDRESS_NO_PORT, [1], 4) = 0
bind(5, {sa_family=AF_INET, sin_port=htons(0), sin_addr=inet_addr("127.0.0.2")}, 16) = 0
getsockname(5, {sa_family=AF_INET, sin_port=htons(0), sin_addr=inet_addr("127.0.0.2")}, [16]) = 0
connect(5, {sa_family=AF_INET, sin_port=htons(53174), sin_addr=inet_addr("127.0.0.3")}, 16) = 0
getsockname(5, {sa_family=AF_INET, sin_port=htons(38050), sin_addr=inet_addr("127.0.0.2")}, [16]) = 0
IPv6 test :
socket(PF_INET6, SOCK_STREAM, IPPROTO_IP) = 7
setsockopt(7, SOL_IP, IP_BIND_ADDRESS_NO_PORT, [1], 4) = 0
bind(7, {sa_family=AF_INET6, sin6_port=htons(0), inet_pton(AF_INET6, "::1", &sin6_addr), sin6_flowinfo=0, sin6_scope_id=0}, 28) = 0
getsockname(7, {sa_family=AF_INET6, sin6_port=htons(0), inet_pton(AF_INET6, "::1", &sin6_addr), sin6_flowinfo=0, sin6_scope_id=0}, [28]) = 0
connect(7, {sa_family=AF_INET6, sin6_port=htons(57300), inet_pton(AF_INET6, "::1", &sin6_addr), sin6_flowinfo=0, sin6_scope_id=0}, 28) = 0
getsockname(7, {sa_family=AF_INET6, sin6_port=htons(60964), inet_pton(AF_INET6, "::1", &sin6_addr), sin6_flowinfo=0, sin6_scope_id=0}, [28]) = 0

instead of ~32000 before patch.

====================
Free VI, flush sge ec and some other misc. fixes
This patch series adds the following.
Free VI interface during remove, flush SGE ec routine, rename
t4_link_start to t4_link_l1cfg since it only does l1 configuration, set
mac addr from when we can't contact firmware for debug purpose, set pcie
completion timeout and use fw interface to access TP_PIO_XXX registers
This patch series has been created against net-next tree and includes
patches on cxgb4 driver.
