Adds SR-IOV features supported by the 82599 controller to the main driver
module.  If the CONFIG_PCI_IOV kernel option is selected then the SR-IOV
features are enabled.  Use the max_vfs module option to allocate up to 63
virtual functions per physical port.

This patch adds documentation for the MSCAN OF device bindings for

"Documentation/powerpc/dts-bindings/fsl/can.txt".

Signed-off-by: NDavid S. Miller <davem@davemloft.net>

The main differences compared to the MSCAN on the MPC5200 are:

- More flexibility in choosing the CAN source clock and frequency:

  Three different clock sources can be selected: "ip", "ref" or "sys".
  For the latter two, a clock divider can be defined as well. If the
  clock source is not specified by the device tree, we first try to
  find an optimal CAN source clock based on the system clock. If that
  is not possible, the reference clock will be used.

- The behavior of bus-off recovery is configurable:

  To comply with the usual handling of Socket-CAN bus-off recovery,
  "recovery on request" is selected (instead of automatic recovery).

Note that only MPC5121 Rev. 2 and later is supported.

The start_xmit function of the MSCAN Driver did return improperly if
the CAN dlc check failed (skb not freed and invalid return code). This
patch adds a proper check of the frame lenght and data size and returns
now correctly. The invalid skb packets are dropped silently as suggested
by David Miller in the thread "[RFC] ndo_validate_skb: Let the netdev
check a valid skb content" on the netdev mailing list.

Furthermore, a typo has been fixed.

General cleanup of the ep93xx_eth driver.

1) Use pr_fmt() to prefix the module name and __func__ to the error 
   messages.
2) <linux/io.h> instead of <asm/io.h>
3) <mach/hardware.h> instead of <mach/ep93xx-regs.h> and <mach/platform.h>
4) Move the ep93xx_mdio_read (and ep93xx_mdio_write) function to eliminate
   the function prototype.
5) Change all the printk(<level> messages to pr_<level> and remove the 
   __func__ argument.
6) Use platform_get_{resource/irq} to get the platform resources and add
   an error check.
7) Use resource_size() for request_mem_region() and ioremap().
8) Use %pM to print the MAC address at the end of the probe.
9) Use dev->dev_addr not data->dev_addr for the MAC argument because a
   random address could be used if the platform does not supply one.

The message at the end of the probe is left as a printk since it displays
cleaner without the function name that would be displayed with pr_info().

The MSI-X table size needs to be properly set before pci_enable_msix()
is called.  But on certain machines, the writes are delayed and the
MSI-X table size is incorrectly read.  By reading the
BNX2_PCI_MSIX_CONTROL register, the writes are flushed and now
ensure that the MSI-X table is set correctly before MSI-X
is enable on the device.
