nl80211: Generate deauth/disassoc event for locally generated frames
Jouni Malinen [Fri, 27 Mar 2009 18:53:56 +0000 (20:53 +0200)]
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.
