Hmm.. if I assume ath10k_sta_state() isn't called for AUTH->ASSOC
(which probably isn't unreasonable to consider since IBSS doesn't have
an association sequence, does it?) then ath10k_station_assoc() isn't
called and neither is ath10k_wmi_peer_assoc() which I suspect setups
HW rate control.

Can you check if the ath10k_wmi_peer_assoc() is called or not and what
are the station state transitions (I think mac80211 traces provide the
transition debug)?
