bnx2x: Fix PF-VF communication over multi-cos queues.
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. Signed-off-by: Manish Chopra <manishc@marvell.com> Signed-off-by: David S. Miller <davem@davemloft.net>
