See the file drivers/ar6000/wmi/wmi_doc.h:
Indicates that the AR6000 device is prepared to accept commands.
It is sent once after
power on or reset. It also indicates the MAC address of the device.
Device MAC address
A WMI_PHY_CAPABILITY value. Indicates the
capabilities of the device wireless module's radio
You could try to change the ready function in wmi.c to use a mac
address of your own.
