Jeff Kirsher says:

====================
40GbE Intel Wired LAN Driver Updates 2016-12-02

This series contains updates to i40e and i40evf only.

Alex provides changes so that we are much more robust about defining what
we can and cannot offload in i40e and i40evf by doing additional checks
other than L4 tunnel header length.

Jake provides several fixes/changes, first cleaning up a label that is
unnecessary, as well as cleaned up the use of a "magic number".  Clarified
the code by separating the global private flags and the regular private
flags per interface into two arrays, so that future additions will not
produce duplication and buggy code.  Adds additional checks to protect
against NULL values for msix_entries and q_vectors pointers.

Michal adds Clause22 method for accessing registers for some external
PHYs.

Piotr adds additional protocol support for the admin queue discover
capabilities function.

Tushar Dave fixes a panic seen on SPARC, where writel() should not be
used to write directly to a memory address but only to a memory mapped
I/O address otherwise it causes data access exceptions.

Joe Perches separates out a section of code into its own function, to
help reduce i40evf_reset_task() a bit.

Alan fixes an issue by checking for NULL before dereferencing msix_entries
and returning early in the case where it is NULL within the i40evf_close()
code path.

Henry provides code cleanup to remove unreachable and redundant sections
of code.  Fixed up an issue where new NICs were not identifying "unknown
PHYs" correctly.

Harshitha fixes a issue where the ethtool "Supported Link" modes list
backplane interfaces on X722 devices for 10 GbE with SFP+ and Cortina
retimer, where these interfaces should not be visible to the user since
they cannot use them.

Carolyn changes an X722 informational message so that it only appears
when extra messages are desired.
