From: Johannes Berg <johannes.berg@xxxxxxxxx> commit 77e7b6ba78edf817bddfa97fadb15a971992b1ee upstream. Prior to commit 7b0a0e3c3a88 ("wifi: cfg80211: do some rework towards MLO link APIs") the interface type didn't really matter here, but now we need to handle all of the possible cases. Add IBSS ("ADHOC") and handle it.
