From 53b46b8444f600cc1744521ea096ea0c5d494dd0 Mon Sep 17 00:00:00 2001 From: Jouni Malinen Date: Fri, 27 Mar 2009 20:53:56 +0200 Subject: nl80211: Generate deauth/disassoc event for locally generated frames Previously, nl80211 mlme events were generated only for received deauthentication and disassociation frames. We need to do the same for locally generated ones in order to let applications know that we disconnected (e.g., when AP does not reply to a probe). Rename the nl80211 and cfg80211 functions (s/rx_//) to make it clearer that they are used for both received and locally generated frames. Signed-off-by: Jouni Malinen Signed-off-by: John W.
