<div class='commit-subject'>ixgbevf: get rid of custom busy polling code</div><div class='commit-msg'>In linux-4.5, busy polling was implemented in core
NAPI stack, meaning that all custom implementation can
be removed from drivers.

Not only we remove lot's of code, we also remove one lock
operation in fast path, and allow GRO to do its job.
