Merge branch 'bnxt_en-Bug-fixes' 

Michael Chan says:

====================
bnxt_en: Bug fixes.

A series of small driver fixes covering VPD length logic,
ethtool_get_regs on VF, hwmon temperature error handling,
mutex locking for EEE and pause ethtool settings, and
parameters for statistics related firmware calls.

Please queue patches 1, 2, and 3 for -stable.  Thanks.
====================
