Change 45447 by sam at sam_ebb on 2004/01/16 09:29:45

	when changing modes reset the rate set so drivers have
	view consistent with ic_ibss_chan; this eliminates the
	need for the hack in the ath driver where it recovers
	when the rate set is empty and also fixes a problem where
	you switch modes while operating in hostap mode
