the only thing that bugs me is this:

BSS 00:1c:f0:xx:xx:xx (on wlan0)

I didn't find any specs to decode IE 45 and 61 since all of them mark
these as reserved. Not sure if these are defined in future specs or if
they are deprecated IE. And it seems its data is similar to what is in
the vendor specific elements.

The other one that keeps showing up in my area is:

	Unknown IE (47): 06

And I do have some other vendor specific ones, that I don't really care
about and we might even never know what they are:

	Vendor specific: OUI 00:03:7f, data: 01 01 00 17 00 00
	Vendor specific: OUI 00:03:7f, data: 02 01 01 4d 00 03 a4 00 00
	Vendor specific: OUI 00:03:2f, data: 01 00 01

However, as I said before, I am quite happy now since the provided
information by iw are now the same as I get with iwlist. Actually iw has
now superior decoding capabilities and is more useful. There is still
room for improvement, but I think cutting a new release is not a bad
idea.

Regards

Marcel
