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 2018-03-19

This series contains updates to i40e and i40evf only.

Alex fixes a potential deadlock in the configure_clsflower function in
i40evf, where we exit with the "IN_CRITICAL_TASK" bit set while
notifying the PF of flower filters.

Jan fixed an issue where it was possible to set a mode that is not
allowed which resulted in link being down, so fixed the parity between
i40e_set_link_ksettings() and i40e_get_link_ksettings().

Patryk fixes a bug where a backplane device was allowing the setting of
link settings, which is not allowed.

Shiraz fixes a crash when entering S3 because the client interface was
freeing the MSIx vectors while they are still in use.

Jake fixes up a function header comment to document a newly added
parameter.  Also cleaned up flags that were never used.

Doug fixes the incorrect return type for i40e_aq_add_cloud_filters().
