nl80211: Event notifications for MLME events
Add new nl80211 event notifications (and a new multicast group, "mlme") for informing user space about received and processed Authentication, (Re)Association Response, Deauthentication, and Disassociation frames in station and IBSS modes (i.e., MLME SAP interface primitives MLME-AUTHENTICATE.confirm, MLME-ASSOCIATE.confirm, MLME-REASSOCIATE.confirm, MLME-DEAUTHENTICATE.indicate, and MLME-DISASSOCIATE.indication). The event data is encapsulated as the 802.11 management frame since we already have the frame in that format and it includes all the needed information. This is the initial step in providing MLME SAP interface for authentication and association with nl80211. In other words, kernel code will act as the MLME and a user space application can control it as the SME. Signed-off-by: Jouni Malinen <j@w1.fi> Signed-off-by: John W.
