RSN IBSS is supposed to work and well, works at least with
mac80211_hwsim, but I have not tested with ath9k recently. Anyway, your
configuration has some issues that would likely explain traffic not
working.

While TKIP is allowed, I'd use CCMP with RSN since TKIP does not make
much sense for a case where every single device supporting RSN will also
support CCMP. Anyway, the larger issue is with pairwise=NONE. That is
not really something I would have ever tested with RSN IBSS since proper
pairwise encryption should be used with RSN STAs. In other words,
replace those with pairwise=CCMP and group=CCMP to make this more
meaningful.
