* [patch net-next-2.6 14/47] cxgb4vf: do vlan cleanup
From: Jiri Pirko @ 2011-07-20 14:54 UTC (permalink / raw)
To: netdev; +Cc: davem, shemminger, eric.dumazet, greearb, mirqus, leedom
In-Reply-To: <1311173689-17419-1-git-send-email-jpirko@redhat.com>
- unify vlan and nonvlan rx path
- kill pi->vlan_grp and cxgb4vf_vlan_rx_register
- allow to turn on/off rx/tx vlan accel via ethtool (set_features)
