Subject: [PATCH] net/bnx2x: fix FW command timeout during stop
[ upstream commit 4a4607bb9cadcc49a062a46588dbdcc873dfe27a ]
This patch fixes firmware command timeout error seen during device stop
while stopping queues. It patially reverts an earlier preventive change
commit 91b7e432bcef ("net/bnx2x: disable fast path interrupts") to now
enable fast path interrupts.
The original issue of performance degradation is not observed anymore,
with or without the fix.
Fixes: 91b7e432bcef ("net/bnx2x: disable fast path interrupts")
