This patch allows the driver to pass that state in cfg80211_connect_done() resulting in adding the new flag NL80211_ATTR_PORT_AUTHORIZED in the NL80211_CMD_CONNECT notification. For 802.1X the driver is expected to issue the NL80211_CMD_CONNECT notification twice. First without the new attribute to inform user-space that 802.1X authentication can start and a second one with the new attribute to indicate the completion of the handshakes.
