====================
40GbE Intel Wired LAN Driver Updates 2015-12-12

This series contains updates to i40e and i40evf only.

Jesse fixes some trivial static analyzer warnings where BIT() can be used
instead of BIT_ULL().

Mitch fixes the virtual channel interface which was using incorrect semantics
to remove MAC addresses and would leave incorrect filters active when using
VLANs.  Also fixes an issue that when VF's are created, the MAC address
defaults to all zeros, indicating to the VF driver that it should use a
random MAC address.  However, the PF driver was incorrectly adding this
zero MAC to the filter table, so check for a good address before adding
the default filter.  Adds a check to make sure that the Tx and Rx rings
actually exist before dereferencing them to free resources.  Re-classifies
several messages which are really for debugging purposes, especially since
the driver can fully recover from any of these.  Fixed up the VF version
strings to match the PF driver.

Anjali adds a virtchnl offload to support the expanded version of TCP/UDP
PCTYPES for RSS.

Shannon fixes i40e to clean the whole MAC filter list when resetting after
an intermediate add or delete push to the firmware.

v2: added blank line after variable declaration in patch 9 based on
    feedback from Sergei Shtylyov <sergei.shtylyov@cogentembedded.com>
