Merge branch '1GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/net-queue
Tony Nguyen says:
====================
Intel Wired LAN Driver Updates 2022-11-30 (e1000e, igb)
This series contains updates to e1000e and igb drivers.
Akihiko Odaki fixes calculation for checking whether space for next
frame exists for e1000e and properly sets MSI-X vector to fix failing
ethtool interrupt test for igb.
* '1GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/net-queue:
igb: Allocate MSI-X vector when testing
e1000e: Fix TX dispatch condition
