Merge branch '40GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/next-queue

Jeff Kirsher says:

====================
40GbE Intel Wired LAN Driver Updates 2019-04-16

This series contains updates to i40e driver only.

Adam fixes i40e so that queues can be restored to its original value if
configuring queue channels fails.  Bumped the maximum API version
supported and added the API version to error messages to clarify
supported firmware API versions.  Fixed the problem with the driver
being able to add only 7 multicast MAC address filters instead of 16.

Aleksandr adds support for Dynamic Device Personalization (DDP) which
allows loading profiles that change the way internal parser interprets
processed frames.

Nick fixes an issue where if we modify the VLAN stripping options when a
port VLAN is configured, it will break traffic for the VSI, so prevent
changes from being made.

Jake fixes an issue where a device reset can mess up the clock time
because we reset the clock time based on the kernel time every reset.
This causes us to potentially completely reset the PTP time, and can
cause unexpected behavior in programs like ptp4l.

Piotr fixes an LED blink issue with the 'ethtool -p' command, so that
identification blinking will work on all hardware.

Chinh fixed the error returned to correctly reflect the current state
when LLDP or DCBx is not in an operational state.

Grzegorz cleans up a misleading error message when untrusted VF tries to
exceed addresses beyond the NIC limit.

Carolyn fixes the error return code to correctly reflect the error case.

v2: updated the URL provided in the DDP patch (#2)
