Subject: [PATCH] nl80211: allow sending CMD_FRAME without specifying any
 frequency

Users may want to send a frame on the current channel
without specifying it.

This is particularly useful for the correct implementation
of the IBSS/RSN support in wpa_supplicant which requires to
receive and send AUTH frames.

Make mgmt_tx pass a NULL channel to the driver if none has
been specified by the user.
