it only makes sense if you set a single fixed rate.

a TX bitrate mask has been added to iw in version 0.9.21:
commit 0db5d893ecf2ce4538af6fdcae3d94f2f83757e2
Author: Johannes Berg <johannes@xxxxxxxxxxxxxxxx>
Date: Fri Sep 24 17:44:07 2010 +0200
version 0.9.21
* transmit power support
* TX bitrate mask support
* more informative scan output
* make it build on old systems
you can use it like this, e.g.: "iw wlan0 set bitrates legacy-2.4 12 18 24"
this is much more flexible than the iwconfig way, as it allows a bitmap of TX
rates which can be used. again this is a reason why it does not make sense to
show a single TX bitrate, but i guess this TX bitmap could/should be shown
somewhere.
