* force the use of the primary MAC address for a station mode
* interface, we need some other way of configuring a per-interface
* remote BSSID.
* The hardware provides an AP-Client feature, where bssidx 0-7 are
* used for AP mode and bssidx 8-15 for client mode.
* We shift the station interface bss index by 8 to force the
* hardware to recognize the BSSID.
* The resulting bssidx mismatch for unicast frames is ignored by hw.
