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.
