From f21293549f60f88c74fcb9944737f11048896dc4 Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Wed, 1 Jul 2009 21:26:56 +0200 Subject: [PATCH] cfg80211: managed mode wext compatibility This adds code to make it possible to use the cfg80211 connect() API with wireless extensions, and because the previous patch added emulation of that API with auth() and assoc(), by extension also supports wext on that. At the same time, removes code from mac80211 for wext, but doesn't yet clean up mac80211's mlme code more. Signed-off-by: Samuel Ortiz Signed-off-by: Johannes Berg Signed-off-by: John W.
