NL80211_CMD_SET_WIPHY and NL80211_CMD_GET_WIPHY to manage

+ * 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 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_MICHAEL_MIC_FAILURE: notification of a locally detected Michael
