Merge branch '40GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/net-queue
 
Jeff Kirsher says:

====================
Intel Wired LAN Driver Updates 2020-06-11

This series contains fixes to the iavf driver.

Brett fixes the supported link speeds in the iavf driver, which was only
able to report speeds that the i40e driver supported and was missing the
speeds supported by the ice driver.  In addition, fix how 2.5 and 5.0
GbE speeds are reported.

Alek fixes a enum comparison that was comparing two different enums that
may have different values, so update the comparison to use matching
enums.

Paul increases the time to complete a reset to allow for 128 VFs to
complete a reset.
