when an IBSS merge happened, the supported rates for the newly added station

the basic rates.
also the section of the ibss code which deals with updating supported rates for
an already existing station fails to inform the rate control module about the
new rates. as i don't know how to fix this (minstrel does not have an update
function), i have just added a comment for now.

This seems like a stable fix, if it applies can you please resend with a

Hi Bruno,
I think the root cause is that IBSS neighbor entries are added whenever
we received any packet from a neighbor. However, the supported rates are
only available in the beacon/probe responses. I think one fix is to only
add IBSS neighbors on beacon/probe response reception (and moreover,
beacon/probe responses contains the timestamp that is needed for IBSS
merge).
Basically, I removed the call to ieee80211_ibss_add_sta in
net/mac80211/rx.c.
Can you try that and tell me about the result?
In fact, I did this change to have HT rates in IBSS mode (but I'm still
missing some stuff).
Regards,
Benoit
