3.16.55-rc1 review patch. If anyone has any objections, please let me know.
------------------ From: Oliver Stäbler <[email protected]> commit f6c23b174c3c96616514827407769cbcfc8005cf upstream. After commit d75b1ade567f ("net: less interrupt masking in NAPI") napi repoll is done only when work_done == budget. So we need to return budget if there are still packets to receive.
