mac80211: add support for mcs masks
* Handle MCS masks set by the user. * Match rates provided by the rate control algorithm to the mask set, also in HT mode, and switch back to legacy mode if necessary. * add debugfs files to observate the rate selection Signed-off-by: Simon Wunderlich <siwu@hrz.tu-chemnitz.de> Signed-off-by: Mathias Kretschmer <mathias.kretschmer@fokus.fraunhofer.de> Signed-off-by: John W.
