Jeff Kirsher says:

====================
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

Wake on LAN is disabled by default and will remain that way for most
platforms, but there is an NVM setting that allows vendors to enable it
for a port if they think they've provided the right power environment

The following series implements the last set of bonding netlink attributes

lacp_rate
ad_select
ad_info, nest of:
ad_aggregator
ad_num_ports
ad_actor_key
ad_partner_key
ad_partner_mac

The last patch adds an additional netlink attribute, active_slaves, which
is a nested list of ifindices for current active slaves.  We're using this
list to enable/disable hashing of ports in a hardware LAG implementation.
In the same way bonding driver includes/excludes ports for 802.3ad egress

ipv4: arp: update neighbour address when a gratuitous arp is received and arp_accept is set

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.

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.
