Subject[PATCH 5.2 09/56] bnx2x: Disable multi-cos feature.
Date
From: Sudarsana Reddy Kalluru <skalluru@marvell.com>

[ Upstream commit d1f0b5dce8fda09a7f5f04c1878f181d548e42f5 ]

Commit 3968d38917eb ("bnx2x: Fix Multi-Cos.") which enabled multi-cos
feature after prolonged time in driver added some regression causing
numerous issues (sudden reboots, tx timeout etc.) reported by customers.
We plan to backout this commit and submit proper fix once we have root
cause of issues reported with this feature enabled.
