	All of the other drivers display only a single line, and
SoftMAC is the odd one here. I think that have the info twice may
confuse some tools.
	I know that there are scripts that parse iwlist output,
however I'm not keen on the practice, as there are alternatives.

	Unfortunately, I can't guarantee that. I can only guarantee
that it will be similar to what other drivers do.
