I don't think OCB should be treated like STA/Ad-Hoc for ANI purposes.
In fact, I think most places inside ath9k_hw should treat OCB the same
as AP - maybe even by leaving ah->opmode at NL80211_IFTYPE_AP for OCB.

Why treat OCB like Ad-hoc for STA_ID1?

Enabling the TSFOOR interrupt for OCB seems completely wrong to me. If I
understand this mode correctly, there are no beacons, hence no TSF
synchronization.
