PATCH 1/1 Set floor of wireless signal and noise at -110 dBm

John,

Please apply to wireless-2.6.

Thanks, Larry

===========================================

This patch sets the floor of wireless level (signal) and noise at -110 dBm, which makes them be comatible with RCPI, as discussed by Simon Barber. With this change, bcm43xx-softmac and bcm43xx-d80211 behave the same.
