signal quality statistics patch for 2002-04-05

Based on the formulas from wvlan_cs and post from Jodi Morgo I have made a patch against 2002-04-05 to retrieve signal, noise & quality statistics.

Please find it attached.

The reason I decided to use formulas from wvlan_cs as they seem to be more correct to me. Quality value for prism2 never went above 92 in my tests and wvlan_cs formulas seem to compensate for that. I also changed maximum for quality (max_qual.qual) to 0x5C (92) as per wvlan_cs driver.

In any case original formulas as posted by Jodi Morgo are available (I commented them out).

Best Regards
Vladimir Ivaschenko
