Both used in the "get_omac_idx"-function: if (~mask & BIT(HW_BSSID_0)) return HW_BSSID_0; With commit d8d59f66d136 ("mt76: mt7615: support 16 interfaces") the adhoc and meshpoint mode should "prefer hw bssid slot 1-3". However, with that change the ibss or meshpoint mode will not send any beacon on the mt7622 wifi anymore. Devices were still able to exchange data but only if a bssid already existed. Two mt7622 devices will never be able to communicate. This commits reverts the preferation of slot 1-3 for adhoc and meshpoint. Only NL80211_IFTYPE_STATION will still prefer slot 1-3. Tested on Banana Pi R64.
