[ Upstream commit c3d897e01aef8ddc43149e4d661b86f823e3aae7 ]
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")
