I have been reading their code, but it is a completely different code base
from our our urtwn code and without hardware documents (any one have
some to share????) it is a little difficult seeing what they are doing.  I will
look closer for this issue for the rssi at some point.

p.s.  FreeBSD only has a urtw driver and it covers a lot fewer devices than
the NetBSD urtwn driver.
