From 1a31f2042e938f1b467aa3d807cc5666352bf8a3 Mon Sep 17 00:00:00 2001 From: Stephen Hemminger <shemminger@vyatta.com> Date: Mon, 13 Apr 2009 18:12:57 -0700 Subject: netsched: Allow meta match on vlan tag on receive When vlan acceleration is used on receive, the vlan tag is maintained outside of the skb data. The existing vlan tag match only works on TX path because it uses vlan_get_tag which tests for VLAN_HW_TX_ACCEL. Signed-off-by: Stephen Hemminger <shemminger@vyatta.com> Signed-off-by: David S.
