From: Luis Henriques
Date: Thu Feb 19 2015 - 08:52:50 EST

3.16.7-ckt7 -stable review patch. If anyone has any objections, please let me know.


From: Govindarajulu Varadarajan <_govind@xxxxxxx>

commit 24e579c8898aa641ede3149234906982290934e5 upstream.

With the commit d75b1ade567ffab ("net: less interrupt masking in NAPI") napi
repoll is done only when work_done == budget. When in busy_poll is we return 0
in napi_poll. We should return budget.
