Review the patch:

nl80211: New command for setting TX rate mask for rate control
Add a new NL80211_CMD_SET_TX_BITRATE_MASK command and related
attributes to provide support for setting TX rate mask for rate
control. This uses the existing cfg80211 set_bitrate_mask operation
that was previously used only with WEXT compat code (SIOCSIWRATE). The
nl80211 command allows more generic configuration of allowed rates as
a mask instead of fixed/max rate.

I think that addresses this, not sure if we ever got the iw equivalent
patches to let userspace use this yet.
There are however three wext things which we still do need implement to nl80211:
iwconfig wlan0 txpower 17 # sets TX output power to 17 dBm
iwconfig wlan0 power off # disables power save
iwconfig wlan0 power 500m # enables dynamic power wave with 500ms idle
timeout trigger
I've stuffed this int our todo list [1], if you confirm that the above
patch does not yet address what you wish please add it to the todo
list.
