bnx2x: Fix Multi-Cos
Apparently multi-cos isn't working for bnx2x quite some time - driver implements ndo_select_queue() to allow queue-selection for FCoE, but the regular L2 flow would cause it to modulo the fallback's result by the number of queues. The fallback would return a queue matching the needed tc [via __skb_tx_hash()], but since the modulo is by the number of TSS queues where number of TCs is not accounted, transmission would always be done by a queue configured into using TC0. Fixes: ada7c19e6d27 ("bnx2x: use XPS if possible for bnx2x_select_queue instead of pure hash") Signed-off-by: Yuval Mintz <Yuval.Mintz@cavium.com> Signed-off-by: David S. Miller <davem@davemloft.net>
