	Who sent the beacon is different from who created the IBSS. If
you don't like this proposal, here is another one : if in ad-hoc mode
the actual IBSS freq is the same as what the user set, then set the
'fixed' flag, otherwise report the actual freq without the 'fixed'
flag.
	Or if you have another meaningful use of the flag in ad-hoc
mode, just shout.
