====================
Intel Wired LAN Driver Updates 2017-06-06

This series contains fixes to i40e and i40evf only.

Mauro S. M. Rodrigues fixes a flood in the kernel log which was introduced
in a previous commit because of a mistaken substitution of __I40E_VSI_DOWN
instead of __I40E_DOWN when testing the state of the PF.

Björn Töpel fixes an issue introduced in a previous commit where the
offset was incorrect and could lead to data corruption for architectures
using PAGE_SIZE larger than 8191.  Fixed the issue by updating the
page_offset correctly using the proper setting for truesize.
