hv_netvsc: Fix the queue_mapping in netvsc_vf_xmit()
netvsc_vf_xmit() / dev_queue_xmit() will call VF NIC’s ndo_select_queue or netdev_pick_tx() again. They will use skb_get_rx_queue() to get the queue number, so the “skb->queue_mapping - 1” will be used. This may cause the last queue of VF not been used. Use skb_record_rx_queue() here, so that the skb_get_rx_queue() called later will get the correct queue number, and VF will be able to use all queues. Fixes: b3bf5666a510 ("hv_netvsc: defer queue selection to VF") Signed-off-by: Haiyang Zhang <haiyangz@microsoft.com> Signed-off-by: David S. Miller <davem@davemloft.net>
