Merge branch 'bnxt_en-Bug-fixes'

Michael Chan says:

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

The first patch stores the firmware version code which is needed by the
next 2 patches to determine some worarounds based on the firmware version.
The workarounds are to disable legacy TX push mode and to clear the
hardware statistics during ifdown.  The last patch checks that it is
a PF before reading the VPD.

Please also queue these for -stable.  Thanks.
