I write here since I am currently performing experiments in which I need
specifically to disable RTS frames. Intuitively, I tried to set
iw phyXX set rts off
but btained counter-intuitive results, since RTS effectively
dissappeared
only for low traffic demands from upper layers (around 1Mbps with 3
nodes). Testing with 3 Mbps makes the RTS appear despite the RTS "off"
setting from iw.
Is there a way to set minstrel_ht not to use RTS (no matter the clever
or not it be) ?
I have searched for a while on the archive but this seems the only
conversation that deals with that.
Thank you very much for any information!

If you send a patch for that, I'm ok with it. The default should be RTS
off, but rc may still use it.
