Jeff Kirsher says:

====================
1GbE Intel Wired LAN Driver Updates 2017-04-30

This series contains updates to e1000e only.

Jarod Wilson fixes an issue where the workaround for 82574 & 82583
is needed for i218 as well, so set the appropriate flags.

Sasha adds support for the upcoming new i219 devices for the client
platform (CannonLake), which includes the support for 38.4MHz frequency
to support PTP on CannonLake.
