From 0fbe0d47b1ee2015c288abd4e7b32224f8bfa212 Mon Sep 17 00:00:00 2001 From: Jason Wang Date: Tue, 16 Jul 2013 13:36:34 +0800 Subject: [PATCH] macvtap: do not assume 802.1Q when send vlan packets The hard-coded 8021.q proto will break 802.1ad traffic. So switch to use vlan->proto. Cc: Basil Gor Signed-off-by: Jason Wang Signed-off-by: David S.
