This patch improves the statistics returned from bcm43xx_get_wireless_stats. The signal level comes from smoothing the "rssi" value returned by the firmware after it is converted into a dBm value by the driver. The quality value is a hack derived from the smoothed level and an assumed RX_POWER_MAX of -10 dBM. The noise value is still the one calculated from the clean-room formula. On my system, this is roughly -65 dBm, which seems too high. The revised version uses the ieee80211 spinlock to protect traversing of the network list.

README ------ This directory is mostly for Wireless LAN drivers, in their various incarnations (ISA, PCI, Pcmcia...). This separate directory is needed because a lot of driver work on different bus (typically PCI + Pcmcia) and share 95% of the code. This allow the code and the config options to be in one single place instead of scattered all over the driver tree, which is never 100% satisfactory. Note : if you want more info on the topic of Wireless LANs, you are kindly invited to have a look at the Wireless Howto : http://www.hpl.hp.com/personal/Jean_Tourrilhes/Linux/ Some Wireless LAN drivers, like orinoco_cs, require the use of Wireless Tools to be configured : http://www.hpl.hp.com/personal/Jean_Tourrilhes/Linux/Tools.html Special notes for distribution maintainers : 1) wvlan_cs will be discontinued soon in favor of orinoco_cs 2) Please add Wireless Tools support in your scripts Have fun...
