If anyone has any objections, please let me know. ------------------ [ Upstream commit fb1faab74ddef9ec2d841d54e5d0912a097b3abe ] Max supported queues is derived incorrectly in the case of multi-CoS. Need to consider TCs while calculating num_queues for PF. Signed-off-by: Sudarsana Reddy Kalluru <skalluru@xxxxxxxxxxx> Signed-off-by: Ariel Elior <aelior@xxxxxxxxxxx> Signed-off-by: David S.
