Subject: [PATCH AUTOSEL 5.4 212/350] bnx2x: Fix PF-VF communication over multi-cos queues.
From: Manish Chopra <manishc@...vell.com>
[ Upstream commit dc5a3d79c345871439ffe72550b604fcde9770e1 ]
PF driver doesn't enable tx-switching for all cos queues/clients,
which causes packets drop from PF to VF. Fix this by enabling
tx-switching on all cos queues/clients.
