Intel Wired LAN Driver Updates 2014-06-09

This series contains more updates to i40e and i40evf.

Shannon adds checks for error status bits on the admin event queue and
provides notification if seen.  Cleans up unused variable and memory
allocation which was used earlier in driver development and is no longer
needed.  Also fixes the driver to not complain about removing
non-existent MAC addresses.  Bumps the driver versions for both i40e
and i40evf.

Catherine fixes a function header comment to make sure the comment correctly
reflects the function name.

Mitch adds code to allow for additional VSIs since the number of VSIs that
the firmware reports to us is a guaranteed minimum, not an absolute
maximum.  The hardware actually supports for more than the reported value,
which we often need.  Implements anti-spoofing for VFs for both MAC
addresses and VLANs, as well as enable this feature by default for all VFs.

Anjali changes the interrupt distribution policy to change the way
resources for special features are handled.  Fixes the driver to not fall
back to one queue if the only feature enabled is ATR, since FD_SB
and FD_ATR need to be checked independently in order to decide if we
will support multiple queue or not.  Allows the RSS table entry range
and GPS to be any number, not necessarily a power of 2 because hardware
does not restrict us to use a power of 2 GPS in the case of RSS as long as
we are not sharing the RSS table with another VSI (VMDq).

Frank modifies the driver to keep SR-IOV enabled in the case that RSS,
VMFq, FD_SB and DCB are disabled so that SR-IOV does not get turned off
unnecessarily.

Jesse fixes a bug in receive checksum where the driver was not marking
packets with bad checksums correctly, especially IPv6 packets with a bad
checksum.  To do this correctly, we need a define that may be set by
hardware in rare cases.

Greg fixes the driver to delete all the old and stale MAC filters for the
VF VSI when the host administrator changes the VF MAC address from under
its feet.
