====================
Intel Wired LAN Driver Updates
This series contains updates to i40e and pci_regs.h.
Anjali provides a patch to prevent messages from stray HMC events, except
at interrupt message level, and refactors the HMC error handling.
Catherine adds routines in probe to populate/check PCI bus speed and width,
then verify we are in a 8GT/s x8 PCIe slot and warn when we are not.
Shannon adds Wake-on-LAN support for i40e, fixes curly brace use as well as
return type for i40e_vsi_clear_rings().
Joseph implements receive offload for VXLAN for i40e, where the hardware
supports checksum offload/verification of the inner/outer header.
Mitch provides the bulk of the changes, where he refactors the VF reset
code so that it works on real hardware. Then does code cleanup by
calling existing functions to enable and disable queues for VFs and
remove unused functions. Removes a unnecessary log messages that are
seen at every VF reset, for example complaining about disabling queues
that are already disabled. Fixes an error return when the VF asks to
add an invalid MAC address and if the VF sends a bad message, make it
more informative about what is actually going on.
Jesse refactors the LED function to flash LED lights correctly.
v2:
- removed patch 5 "i40e: add set settings and pauseparam" based on
feedback from Ben Hutchings, will re-work that patch for later
submission
- Added patch "i40e: Implementation of vxlan ndo's" from Joseph to
address Or Gerlitz's questions and concerns. This patch adds the
implementation for the VXLAN ndo's and allows the hardware to do
receive checksum offload for inner packets on the UDP ports that
VXLAN notifies us about.
- Added patch "i40e: using for_each_set_bit to simplify the code"
from Wei Yongjun. This patch uses for_each_set_bit() to simply
the code.
v3:
- fixed indentation issue in patch 11 based on feedback from
Sergei Shtylyov.
Sorry for the delayed release of v4, it was delayed to the holidays.
v4:
- Addressed Or Gerlitz's concerns about trying to get a hold of a mutex
while holding a spin lock in patch 6 by executing the AQ commands from
a subtask.
- Addressed David Miller's Kconfig concerns by creating a Kconfig VXLAN
option for i40e and wrapped appropriate code with the config option in
patch 6.
- Updated patch 7 based on the changes made in patch 6 in the above two
bullets.
v5:
- Added the patch to pci_regs.h based on David Miller's feedback to add
PCI defines for speed and width
- Updated patch 3 description to better explain the changes based on
feedback from David Miller
- Updated patch 4 to use the newly added defines to pci_regs.h instead
of local defines
- Updated patch 7 to use <net/vxlan.h> in the #include based on feedback

Gratuitous arp packets are useful in switchover scenarios to update
client arp tables as quickly as possible. Currently, the mac address
of a neighbour is only updated after a locktime period has elapsed
since the last update. In most use cases such delays are unacceptable
for network admins. Moreover, the "updated" field of the neighbour
stucture doesn't record the last time the address of a neighbour
changed but records any change that happens to the neighbour. This is
clearly a bug since locktime uses that field as meaning "addr_updated".
With this observation, I was able to perpetuate a stale address by
sending a stream of gratuitous arp packets spaced less than locktime
apart. With this change the address is updated when a gratuitous arp
is received and the arp_accept sysctl is set.

I'm sure the operand slave and bond for the function will not
be NULL, so the check for the bond will not make any sense, so
remove the judgement, and the return value was useless here,
remove the unwanted return value.
The comments for the bond 3ad is too old, cleanup some errors
and warming.

bonding: slight optimizztion for bond_slave_override()
When the skb is xmit by the function bond_slave_override(),
it will have duplicate judgement for slave state, and I think it
will consumes a little performance, maybe it is negligible,
so I simplify the function and remove the unwanted judgement.

bonding: slight optimization for bond_alb_xmit()
The bond_alb_xmit will check the return value for
bond_dev_queue_xmit() every time, but the bond_dev_queue_xmit()
is always return 0, it is no need to check the value every time,
so remove the unneed judgement for the xmit path.

bonding: slight optimization for bond_3ad_xmit_xor()
The bond_dev_queue_xmit() will always return 0, and as a fast path,
it is inappropriate to check the res value when xmit every package,
so remove the res check and avoid once judgement for xmit.

bonding: use ether_addr_equal_unaligned for bond addr compare
Use possibly more efficient ether_addr_equal_64bits
to instead of memcmp.
Modify the MAC_ADDR_COMPARE to MAC_ADDR_EQUAL, this looks more
appropriate.

These patches were tucked-in with me for my long winter's nap!
Please pull them for the 3.14 stream...
For the mac80211 bits, Johannes says:
"Here I just have a collection of fixes/improvements/cleanups, very
little really stands out apart from CSA fixes, vendor command support
and the RCU speedups."
For the iwlwifi bits, Emmanuel says:
"I have hear quite a few things. Alex continues his work on power
management. Arik is reworking the transport API by unifying redudant
APIs and making error handling more generic. Eyal keeps on digging in
the rate scaling code.
We also have two new features - Max is using the brand new generic
cipher infrastructure in mac80211, and Lilach implements the smart fifo
which allows to save power by making interrupt coalescing smarter."
Along with those, Arend and company bring a batch of brcmfmac.
Sujith and Felix bring the usual high level of ath9k activity as well.
Bing gives mwifiex some love as well, and a handful of other bits
get updates here and there.

cnic: Add a signature to indicate valid doorbell offset.
The buffer that is used to pass doorbell offset to the userspace UIO
driver may contain nonzero value in older versions of bnx2x driver.
Userspace cannot easily tell whether it contains a valid doorbell
offset or not. With the added signature, userspace will only use
the doorbell offset if the signature is present.
Update version to 2.5.19.

bnx2: Advertise nothing when speed is forced
The current code does not reset the advertisement register when the speed
is forced, leaving the default advertisement value of 10 Mbps. This does
not work with some link partners when the next patch enables auto-mdix.
Set advertisement register to 0 if the speed is forced.
