From 8d13e670d3fb83f4668c9e37196c3bbf5b9f094c Mon Sep 17 00:00:00 2001 From: John Fastabend Date: Mon, 6 Jun 2011 04:27:16 +0000 Subject: [PATCH] macvlan: add VLAN filters to lowerdev Stacking VLANs on top of the macvlan device does not work if the lowerdev device is using vlan filters set by NETIF_F_HW_VLAN_FILTER. Add ndo ops to pass vlan calls to lowerdev. Signed-off-by: John Fastabend Signed-off-by: David S.
