From 2adb956b084d6d49f519541a4b5f9947e96f8ef7 Mon Sep 17 00:00:00 2001 From: Vlad Yasevich Date: Thu, 27 Mar 2014 22:14:49 -0400 Subject: vlan: Warn the user if lowerdev has bad vlan features. Some drivers incorrectly assign vlan acceleration features to vlan_features thus causing issues for Q-in-Q vlan configurations. Warn the user of such cases.
