b3f4d5990b intel: make wired ethernet driver message level consistent (rev2)
Dan Carpenter noticed that ixgbevf initial default was different than
the rest. But the problem is broader than that, only one Intel driver (ixgb)
was doing it almost right.

The convention for default debug level should be consistent among
Intel drivers and follow established convention.

452427b015 bnx2x: previous driver unload revised
The flow in which the bnx2x driver starts after a previous driver
has been terminated in an 'unclean' manner has several bugs and
FW risks, which makes it possible for the driver to fail after
boot-from-SAN or kdump.
This patch contains a revised flow which performs a safer
initialization, solving the possible crash scenarios.
Notice this patch contains lines with over 80 characters, as it
keeps print-strings in a single line.

52f5509fe8 e1000: fix vlan processing regression
This patch fixes a regression introduced by commit "e1000: do vlan
cleanup (799d531)".

Apparently some e1000 chips (not mine) are sensitive about the order of
setting vlan filter and vlan stripping/inserting functionality. So this
patch changes the order so it's the same as before vlan cleanup.

9e4db1c3ee Merge branch 'platforms' of git://git.linaro.org/people/rmk/linux-arm
Pull ARM platform updates from Russell King:
 "This covers platform stuff for platforms I have a direct interest in
  (iow, I have the hardware).  Essentially:
   - as we no longer support any other Acorn platforms other than RiscPC
     anymore, we can collect all that code into mach-rpc.
   - convert Acorn expansion card stuff to use IRQ allocation functions,
     and get rid of NO_IRQ from there.
   - cleanups to the ebsa110 platform to move some private stuff out of
     its header files.
   - large amount of SA11x0 updates:
   - conversion of private DMA implementation to DMA engine support
     (this actually gives us greater flexibility in drivers over the old
     API.)
   - re-worked ucb1x00 updates - convert to genirq, remove sa11x0
     dependencies, fix various minor issues
   - move platform specific sa11x0 framebuffer data into platform files
     in arch/arm instead of keeping this in the driver itself
   - update sa11x0 IrDA driver for DMA engine, and allow it to use DMA
     for SIR transmissions as well as FIR
   - rework sa1111 support for genirq, and irq allocation
   - fix sa1111 IRQ support so it works again
   - use sparse IRQ support

  After this, I have one more pull request remaining from my current
  set, which I think is going to be the most problematical as it
  generates 8 conflicts."

3c3c10bba1 mtd: add leading underscore to all mtd functions
This patch renames all MTD functions by adding a "_" prefix:

mtd->erase -> mtd->_erase
mtd->read_oob -> mtd->_read_oob
...

The reason is that we are re-working the MTD API and from now on it is
an error to use MTD function pointers directly - we have a corresponding
API call for every pointer. By adding a leading "_" we achieve the following:

1. Make sure we convert every direct pointer users
2. A leading "_" suggests that this interface is internal and it becomes
   less likely that people will use them directly
3. Make sure all the out-of-tree modules stop compiling and the owners
   spot the big API change and amend them.

 5) If SKB recycling is used via napi_reuse_skb() we end up with

    SKB allocation.  Fix from Eric Dumazet.

 6) Fix races in TG3 driver ring refilling, from Michael Chan.

 7) We have callbacks for IPSEC replay notifiers, but some call sites
    were not using the ops method and instead were calling one of the
    implementations directly.  Oops.  Fix from Steffen Klassert.

 8) Fix IP address validation properly in the bonding driver, the
    previous fix only works with netlink where the subnet mask and IP
    address are changed in one atomic operation.  When 'ifconfig' ioctls
    are used the IP address and the subnet mask are changed in two
    distinct operations.  Fix from Andy Gospodarek.

7ae5289017 tg3: Fix RSS ring refill race condition
The RSS feature in tg3 hardware has only one rx producer ring for all
RSS rings.  NAPI vector 1 is special and handles the refilling of the
rx producer ring on behalf of all RSS rings.  There is a race condition
between these RSS NAPIs and the NAPI[1].  If NAPI[1] finishes checking
for refill and then another RSS ring empties the rx producer ring
before NAPI[1] exits NAPI, the chip will be completely out of SKBs in
the rx producer ring.

We fix this by adding a flag tp->rx_refill and rely on napi_schedule()/
napi_complete() to help synchronize it to close the race condition.

Update driver version to 3.123.

The conflicts with pxa are non-obvious, we have multiple branches
adding and removing the same clock settings. According to
Haojian Zhuang, removing the sa1100 rtc dummy clock is the correct
fix here.

df828598a7 netdev: driver: ethernet: Add TI CPSW driver
This patch adds support for TI's CPSW driver.

The three port switch gigabit ethernet subsystem provides ethernet packet
communication and can be configured as an ethernet switch. Supports
10/100/1000 Mbps.

58a3de0592 mlx4_core: fix race on comm channel
Prevent race condition between commands on comm channel.
Happened while unloading the driver when switching from
event to polling mode. VF got completion on the last command
before switching to polling mode, but toggle was not changed.
After the fix - VF will not write the next command before
toggle is updated.

Add compatible string for MPC5125 FEC. The FEC on MPC5125 additionally
supports RMII PHY interface. Configure controller/PHY interface type
according to the optional phy-connection-type property in the ethernet
node. This property should be either "rmii" or "mii".

8f4a0a3d9f ixgbe: Fix issues with SR-IOV loopback when flow control is disabled
This patch allows us to avoid a Tx hang when SR-IOV is enabled.  This hang
can be triggered by sending small packets at a rate that was triggering Rx
missed errors from the adapter while the internal Tx switch and at least
one VF are enabled.

This was all due to the fact that under heavy stress the Rx FIFO never
drained below the flow control high water mark.  This resulted in the Tx
FIFO being head of line blocked due to the fact that it relies on the flow
control high water mark to determine when it is acceptable for the Tx to
place a packet in the Rx FIFO.

The resolution for this is to set the FCRTH value to the RXPBSIZE - 32 so
that even if the ring is almost completely full we can still place Tx
packets on the Rx ring and drop incoming Rx traffic if we do not have
sufficient space available in the Rx FIFO.

8af3c33f4d ixgbe: fix namespace issues when FCoE/DCB is not enabled
Resolve namespace issues when FCoE or DCB is not enabled.
The issue is with certain configurations we end up with namespace
problems. A simple example:

ixgbe_main.c
 - defines func A()
 - uses func A()

ixgbe_fcoe.c
 - uses func A()

ixgbe.h
 - has prototype for func A()

For default (FCoE included) all is good.  But when it isn't the namespace
checker complains about how func A() could be static.

To resolve this, created a ixgbe_lib file to contain functions used
by DCB/FCoE and their helper functions so that they are always in
namespace whether or not DCB/FCoE is enabled.
