Try 2 - Add wireless statistics to d80211 and its drivers

Jiri,

This series of patches address all of your earlier concerns, namely:

1. The d80211 stuff is in Part 1/4, the patches for bcm43xx-d80211 are in Part 2/4, the patches for the adm8211 driver is in Part 3/4, and the patches for the RT2X00 family of drivers are in Part 4/4.

2. The location for maxssi has been moved to struct hw.

3. The unnecessary variables in ieee80211_local have been removed. Unfortunately, wstats has to remain.

4. The floor for signal and noise has been set to -110 dBm.

5. The variables last_signal and last_noise now appear in /sys/class/ieee80211/phy0/sta/[MAC Address]/. BTW, is there a good reason why only root can read these variables?
