qlcnic: support vlan rx accleration
Implemented vlan rx accleration in driver. This helps in increasing significant performance and reduces cpu utilization with GRO and LRO. Eric Dumazet: "Its a bit strange you use dev_kfree_skb_any(skb) here." "We run in NAPI mode, so you can use dev_kfree_skb()." Amit: Done. Using dev_kfree_skb(); Signed-off-by: Amit Kumar Salecha <amit.salecha@qlogic.com> Acked-by: Eric Dumazet <eric.dumazet@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
