[PATCH] d80211: more correct WE support on master interface
From: Jiri Benc <hidden>
Date: 2006-08-03 12:03:06
Master interface needs to have different WE support than virtual interfaces. The current situation leads to Oopses and other strange behaviours because of calling WE functions that shouldn't be supported on master interface.
