====================
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
   from David Miller

Fix the VF reset flow so that it works on real hardware. After
discussions with the HW team, the reset flow has been changed
somewhat.

- Change the i40e_reset_vf function to a void type, and fix
  up the callers to reflect this.
- Move the MSI-X disable code to i40e_free_vf_res since it must
  be done every time the VF is freed, regardless of whether or
  not it is reset.
- Ensure that the PCIe bus is quiet before polling the reset bit.
- Don't clear the VFGEN_RSTAT1 register at the beginning as it is
  cleared by the reset.
- Poll longer for the reset to be done.
- Disable the queues using an existing function rather than
  rolling our own.
- Free and reallocate the VSI after reset to avoid rx hang.

The VF reset code will be refactored in future patches. Part of that
refactor required it to call i40e_alloc_vf_res and i40e_free_vf_res, so
the function must be moved. In order to make the future patches more
readable, we perform the function move here, with no other changes.

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
for the device.  This patch adds code to check the NVM setting and enable
Magic Packet use if WoL is enabled for the port.

Since only Magic Packet is supported, there's not a lot of HW configuration
needed.

====================
bonding: final set of netlink patches

v2:

 - per Jiri's comment, fix ad_select checking against parm table by
   spliting bond_parse_parm() into several funcs.  Go ahead and apply
   same technique to all parameters using parm table.

 - fix netlink msg size to including missing nest attr

 - drop the last patch for active_slaves.  This patch needs to be
   reworked per Jiri's comments and shouldn't hold up finalizing
   the conversion of the existing parameter to netlink attributes.

Ding, assuming this patch set goes in, you should have all you
need to start converting module parameter setting/checking over to
funcs in *_options.c.

I'll send iproute2 patch for bonding netlink support once this patch
set is accepted.

v1:

The following series implements the last set of bonding netlink attributes
for 802.3ad mode:

	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
hashing, hardware ports are included/excluded from egress hashing by
hardware based on port active status.  Yes, data path offloaded to
hardware, control path remains in kernel via bonding driver.
