[PATCH 3.14 10/17] bnx2x: fix napi poll return value for repoll

[Greg Kroah-Hartman <gregkh@linuxfoundation.org>]

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

------------------

From: Govindarajulu Varadarajan <_govind@gmx.com>

[ Upstream commit 24e579c8898aa641ede3149234906982290934e5 ]

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.
