From: Luis R. Rodriguez Date: Mon, 4 Feb 2008 02:51:04 +0000 (-0500) Subject: ath5k: Port to new bitrate/channel API X-Git-Tag: v2.6.26-rc1~1138^2~530^2~108 X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=d8ee398d183df36083e41e9162b0cf014f38f482;p=linux-2.6 ath5k: Port to new bitrate/channel API Author: Nick Kossifidis Tested on 5211, 5213+5112, 5213A+2112A and it wors fine. Also i figured out a way to process rate vallue found on status descriptors, it's still buggy but we are getting closer (i think it improved stability a little).
