From 7033c4ad87c3cf1050eb8190c93f94f5c8b9fae9 Mon Sep 17 00:00:00 2001 From: Jiri Pirko Date: Wed, 20 Jul 2011 04:54:06 +0000 Subject: nes: do vlan cleanup - unify vlan and nonvlan rx path - kill nesvnic->vlan_grp and nes_netdev_vlan_rx_register - allow to turn on/off rx/tx vlan accel via ethtool (set_features) Signed-off-by: Jiri Pirko Signed-off-by: David S.
