As much as I like the idea of having per vif rts/cts settings, the rts/cts
user space API is useless as long as these settings are bluntly ignored by
certain rate control algorithms. I already had to explain to a dozen people
who turned rts/cts off via this API does not really turn it off.
Therefore, I suggest to remove the rts/cts API altogether, so that nobody
falls into the trap of believing this does anything useful.

Marek
