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
