Hi Sven,

But I could be completely wrong about it. It would therefore be
interesting for me to know who would be responsible to start the
queues when ieee80211_do_open rejected it for IBSS.

Well, once ieee80211_offchannel_return() is called, that should do the
needful and end up in ieee80211_propagate_queue_wake().

Can you check what the IBSS vif's queues are (vif->hw_queue[...])?

However, I also don't understand the difference between encrypted and
unencrypted here.
