Merge branch '1GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/next-queue
Jeff Kirsher says:
====================
1GbE Intel Wired LAN Driver Updates 2019-10-29
This series contains updates to e1000e, igb, ixgbe and i40e drivers.
Sasha adds support for Intel client platforms Comet Lake and Tiger Lake
to the e1000e driver. Also adds a fix for a compiler warning that was
recently introduced, when CONFIG_PM_SLEEP is not defined, so wrap the
code that requires this kernel configuration to be defined.
Alex fixes a potential race condition between network configuration and
power management for e1000e, which is similar to a past issue in the igb
driver. Also provided a bit of code cleanup since the driver no longer
checks for __E1000_DOWN.
Josh Hunt adds UDP segmentation offload support for igb, ixgbe and i40e.
