This commit implements the TX side of NL80211_CMD_CONTROL_PORT_FRAME. Userspace provides the raw EAPoL frame using NL80211_ATTR_FRAME. Userspace should also provide the destination address and the protocol type to use when sending the frame. This is used to implement TX of Pre-authentication frames. If CONTROL_PORT_ETHERTYPE_NO_ENCRYPT is specified, then the driver will be asked not to encrypt the outgoing frame. A new EXT_FEATURE flag is introduced so that nl80211 code can check whether a given wiphy has capability to pass EAPoL frames over nl80211.
