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") Signed-off-by: Rasesh Mody <rasesh.mody@cavium.com>
