*
- * @NL80211_CMD_AUTHENTICATE: authentication notification (on the "mlme"
- * multicast group). This event reports reception of an Authentication
+ * @NL80211_CMD_AUTHENTICATE: authentication request and notification.
+ * This command is used both as a command (request to authenticate) and
+ * as an event on the "mlme" multicast group indicating completion of the
+ * authentication process.
+ * When used as a command, %NL80211_ATTR_IFINDEX is used to identify the
+ * interface. %NL80211_ATTR_MAC is used to specify PeerSTAAddress (and
+ * BSSID in case of station mode). %NL80211_ATTR_SSID is used to specify
+ * the SSID (mainly for association, but is included in authentication
+ * request, too, to help BSS selection. %NL80211_ATTR_WIPHY_FREQ is used
+ * to specify the frequence of the channel in MHz. %NL80211_ATTR_AUTH_TYPE
+ * is used to specify the authentication type. %NL80211_ATTR_IE is used to
+ * define IEs (VendorSpecificInfo, but also including RSN IE and FT IEs)
+ * to be added to the frame.
+ * When used as an event, this reports reception of an Authentication
* frame in station and IBSS modes when the local MLME processed the
* frame, i.e., it was for the local STA and was received in correct
* state. This is similar to MLME-AUTHENTICATE.confirm primitive in the
* MLME SAP interface (kernel providing MLME, userspace SME). The
* included NL80211_ATTR_FRAME attribute contains the management frame
* (including both the header and frame body, but not FCS).
- * @NL80211_CMD_ASSOCIATE: association notification; like
- * NL80211_CMD_AUTHENTICATE but for Association Response and Reassociation
- * Response frames (similar to MLME-ASSOCIATE.confirm or
- * MLME-REASSOCIATE.confirm primitives).
- * @NL80211_CMD_DEAUTHENTICATE: deauthentication notification; like
+ * @NL80211_CMD_ASSOCIATE: association request and notification; like
+ * NL80211_CMD_AUTHENTICATE but for Association and Reassociation
+ * (similar to MLME-ASSOCIATE.request, MLME-REASSOCIATE.request,
+ * MLME-ASSOCIATE.confirm or MLME-REASSOCIATE.confirm primitives).
+ * @NL80211_CMD_DEAUTHENTICATE: deauthentication request and notification; like
* NL80211_CMD_AUTHENTICATE but for Deauthentication frames (similar to
- * MLME-DEAUTHENTICATE.indication primitive).
- * @NL80211_CMD_DISASSOCIATE: disassociation notification; like
+ * MLME-DEAUTHENTICATION.request and MLME-DEAUTHENTICATE.indication
+ * primitives).
+ * @NL80211_CMD_DISASSOCIATE: disassociation request and notification; like
* NL80211_CMD_AUTHENTICATE but for Disassociation frames (similar to
- * MLME-DISASSOCIATE.indication primitive).
+ * MLME-DISASSOCIATE.request and MLME-DISASSOCIATE.indication primitives).
