Intel Wired LAN Driver Updates 2014-06-05

This series contains updates to i40e and i40evf.

Jesse fixes an issue reported by Dave Jones where a couple of FD checks
ended up using bitwise OR where it should have been bitwise AND.

Neerav removes unused defines and macros for receive LRO.  Fix the driver
from allowing the user to set a larger MTU size that the hardware was
being configured to support.  Refactors send version which moves code in
two places into a small helper function.

Kamil modifies register diagnostics since register ranges can vary among
the different NVMs to avoid false test results.  So now we try to identify
the full range and use it for a register test and if we fail to define the
proper register range, we will only test the first register from that
group.  Then removes the check for large buffer since this was added in the
case this structure changed in the future, since the AQ definition is now
mature enough that this check is no longer necessary.

Mitch fixes i40evf driver to allocate descriptors in groups of 32 since the
hardware requires it.  Also fixes a crash when the ring size changed because
it would change the count before deallocating resources, causing the driver
to either free nonexistent buffers or leak leftover buffers.  Fixed the
driver to notify the VF for all types of resets so the VF can attempt a
graceful reinit.

Shannon refactors stats collection to create a unifying stats update routine
to call the various stat collection routines.  Removes rx_errors and
rx_missed stats since they were removed from the chip design.  Added
missing VSI statistics that the hardware offers but are not apart of the
standard netdev stats.

v2: dropped patch "i40e: Allow disabling of DCB via debugfs" from Neerav
    based on feedback from David Miller.
