Merge branch 'bnxt_en-Updates'

Michael Chan says:

====================
bnxt_en: Updates.

This series includes simplification and improvement of NAPI polling
logic in bnxt_poll_p5().  The improvements will prevent starving the
async events from firmware if we are in continuous NAPI polling.
The rest of the patches include cleanups, a better return code for
firmware busy, and to clear devlink port type more properly.
