Merge branch 'bnxt_en-fixes'

Michael Chan says:

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

3 small bug fix patches.  The 1st two are aRFS fixes and the last one
fixes a fatal driver load failure on some kernels without PCIe
extended config space support enabled.

Please also queue these for -stable.  Thanks.
