Played with macaddr option in wifi-iface, looks like the above
failure was caused by duplicate BSSID in the air... I used a EEPROM
file from a previous thread and extract MAC address from there.
There is another problem though that if I specify option macaddr for
only one of the two wifi-iface sections, hostapd cannot startup
correctly. Below is the message from netifd/hostapd.
