ixgbevf: get rid of custom busy polling code
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.

attempt to read the memory again from within kernel space. Although there is a HV call to scrub the memory (mem_scrub), there is no easy way to guarantee that the real memory address(es) are not used by other tasks. Clearing the error with mem_scrub would zero the memory and cause the other processes to proceed with bad data. The handling of other non-resumable errors remain unchanged and will cause a panic. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
