From d8ee398d183df36083e41e9162b0cf014f38f482 Mon Sep 17 00:00:00 2001 From: "Luis R. Rodriguez" Date: Sun, 3 Feb 2008 21:51:04 -0500 Subject: 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).

Rodriguez" Date: Sun, 3 Feb 2008 21:51:49 -0500 Subject: ath5k: Cleanup after API changes Cleanup after API changes patch (checkpatch.pl stuff) and on ath5k_hw_channel() make use of the existing ath5k_channel_ok() instead of re-implementing the checks again. This was necessary to make the code cleaner and fit the 80-chars wide limit so sending it within the same patch. Finally make a note that we *may* eventually move cap_range stuff to struct wiphy (band frequency range capabilities). This information can later be exported to userspace, for example, and giving it access to mac80211 and drivers in general can come in handy.
