uli526x: stop using net_device.{base_addr, irq} and convert to __iomem.

The bulk of the patch comes from the __iomem changes.

- the phy read and write operations were carrying the chip id deep
  down the call chain. Let's waste a pointer and contain the flying
  spaghetti monster.
- phy_{read, write}_1bit only need to access the DCR9 register. The loss
  of generality here should not hurt.
- removed a leftover printk of the EISA era. This is a pure PCI device.

net/mlx4_en: Force user priority by QP attribute

Instead of relying on HW to change schedule queue by UP, schedule
queue is fixed for a tx_ring, and UP in WQE is ignored in this aspect.  This
resolves two issues with untagged traffic:
1. untagged traffic has no UP in packet which is needed for QoS. The change
   above allows setting the schedule queue (and by that the UP) of such a stream.
2. BlueFlame uses the same field used by vlan tag. So forcing UP from QPC
   allows using BF for untagged but prioritized traffic.

In old firmware that force UP is not supported, untagged traffic will not subject to
QoS.

Because UP is set by QP, need to always have a tx ring per UP, even if pfcrx
module paramter is false.

stmmac: Define MDC clock selection macros

The patch adds the macros to be used for MDC clock selection. The MDC clock
frequency is based on scaled system clock, and has to be confined to a range
of 1-2.5 MHz. Based on the input CSR clock, the scaling factor has to be
selected.
The platform specific code will provide the default value of this scaling
factor, based on the input CSR clock.
There is an option to set MDC clock higher than the IEEE 802.3 specified
frequency limit of 2.5 MHz. This applies for the interfacing chips that
support higher MDC clocks. The resultant higher clock of 12.5 MHz requires
additional Macros to be defined for the clock divider corresponding to the
to the following selection.
-----------------------------------------
Selection MDC Clock
-----------------------------------------
1000  clk_csr_i/4
1001  clk_csr_i/6
1010  clk_csr_i/8
1011  clk_csr_i/10
1100  clk_csr_i/12
1101   clk_csr_i/14

This support has to be added both in the include file, as well as driver. The
driver need to program the registers based on the interfacing chips. This would

stmmac: Define CSUM offload engine Types

This patch explicitly defines the CSUM offload engine type which need

STMMAC core supports two check sum offload engine types- Type-1 & Type-2.
Also, there are STMMAC cores that do not have the check sum offload
capabilities.

The behaviour of Type-1 & Type-2 cores related to provision of checksum
increases the packet length for Type-1 cores by 2, as the checksum is appended
at the end of data packet and the same is made accountable in the DMA status.
The STMMAC cores beyond Version-3.5 provide HW interface registers which allows
the user to read the HW capabilities, while to support the previous cores the
information related to HW capabilities has to be provided from the platform

information.

ethtool: Introduce a method for getting time stamping capabilities.

This commit adds a new ethtool ioctl that exposes the SO_TIMESTAMPING
capabilities of a network interface. In addition, user space programs
can use this ioctl to discover the PTP Hardware Clock (PHC) device
associated with the interface.

Since software receive time stamps are handled by the stack, the generic
ethtool code can answer the query correctly in case the MAC or PHY
drivers lack special time stamping features.

igb: add PTP Hardware Clock code

This patch adds a source file implementing a PHC. Only the basic
clock operations have been implemented, although the hardware
would offer some ancillary functions. The code is fairly self
contained and is not yet used in the main igb driver.

Every timestamp and clock read operation must consult the overflow
counter to form a correct time value. Access to the counter is
protected by a spin lock, and the counter is implemented using the
standard cyclecounter/timecounter code.
