[PATCH 2.6.11-rc2 2/2] wireless: WEXT quality cleanups + max rssi level fix for at76c502e
From: Dan Williams <hidden>
Date: 2005-02-01 21:56:48
Use correct maximum rssi level for at76c502e-type cards, and correct values in the qual.updated field to more closely match the current Wireless Extensions API. Signed-off-by: Dan Williams <redacted>
