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();
