* | qlcnic: support vlan rx acclerationAmit Kumar Salecha2010-09-173-26/+44
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

| | | | | | | | | | | | | | | | | | | | | | | | | | Device eswitch need to configure with VM's mac address. Hypervisor doesn't provide any utility/callbacks to get VM's mac address. Unicast mac address filter improves performance and also provide packet loopback capability i.e communication between VM. Above features is by default off, can be turned on with module parameter 'mac_learn'. Signed-off-by: Amit Kumar Salecha <amit.salecha@qlogic.com> Signed-off-by: David S. Miller <davem@davemloft.net>
