Merge branch '1GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/net-queue

Tony Nguyen says:

====================
Intel Wired LAN Driver Updates 2020-07-30

This series contains updates to the e1000e and igb drivers.

Aaron Ma allows PHY initialization to continue if ULP disable failed for
e1000e.

Francesco Ruggeri fixes race conditions in igb reset that could cause panics.
