====================
40GbE Intel Wired LAN Driver Updates 2018-05-22

This series contains updates to i40e only.

Jake provides all the changes in this series starting with making it
consistent in how we approach the bit lock.  Fixed the reporting of the
VEB statistics and the queue statistics to always return every queue
even if it is not currently in use.  Use WARN_ONCE() so that the first
time we end up with an incorrect size we will dump a stack trace and a
message to help highlight the issue early in testing.  Folded the fixed
string prefix into the stat string definition.  Instead of using a
separate char *p pointer when copying strings, use the data pointer
directly.  Added code comments for several of the statistic functions to
better explain the number and ordering of statistics.
