cfg80211: implement IWRATE
For now, let's implement that using a very hackish way: simply mirror the wext API in the cfg80211 API. This will have to be changed later when we implement proper bitrate API. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>
