Jeff Kirsher says:

====================
40GbE Intel Wired LAN Driver Updates 2018-02-12

This series contains updates to i40e and i40evf.

Alan fixes a spelling mistake in code comments.  Fixes an issue on older
firmware versions or NPAR enabled PFs which do not support the
I40E_FLAG_DISABLE_FW_LLDP flag and would get into a situation where any
attempt to change any priv flag would be forbidden.

Alex got busy with the ITR code and made several cleanups and fixes so
that we can more easily understand what is going on.  The fixes included
a computational fix when determining the register offset, as well as a
fix for unnecessarily toggling the CLEARPBA bit which could lead to
potential lost events if auto-masking is not enabled.

Filip adds a necessary delay to recover after a EMP reset when using
firmware version 4.33.

Paweł adds a warning message for MFP devices when the link-down-on-close
flag is set because it may affect other partitions.
