From 62f99efce61024f1c645c2c574882b510c77c579 Mon Sep 17 00:00:00 2001 From: Patrick McHardy Date: Mon, 21 Jan 2008 00:22:30 -0800 Subject: [PATCH] [VLAN]: Kill useless check vlan->real_dev is always equal to the device since thats what we used for the lookup. It doesn't even seem worth a WARN_ON or BUG_ON. Signed-off-by: Patrick McHardy Signed-off-by: David S.
