From 87737663d5d7668c8553c572a5a7c26e86c5842b Mon Sep 17 00:00:00 2001 From: Jiri Pirko Date: Wed, 20 Jul 2011 04:54:16 +0000 Subject: [PATCH] cxgb4vf: do vlan cleanup - 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) Signed-off-by: Jiri Pirko Signed-off-by: David S.
