Hello everybody,

sorry for the very late response on this topic.
I am performing some tests now using mac80211_hwsim.
I'm first letting wlan0 join the ibss and then I let wlan1 join the same ibss.
In the log I clearly read that the basic rates get updated by means of a
beacon/probe response (actually this is what I expected).

Then I tried to send frames from wlan0 to wlan1 passing through the emulated
link and I can see with "iw dev wlan0 station dump" that the tx rate gets higher
and higher up to 54mbps. Therefore I do not see any problem with the update of
the basic rates.

Am I missing/overlooking something?
@Sujith, do you have a more clear idea of what the problem is?

Cheers,
