on bcm63xx/HW553 i can chage wired MAC address but not wireless one

[aparcar]

I Own a set of router as subject, that had to be 'jailbreaked' installing a custom CFE via JTAG. Clearly, in this way all router have the same MAC addresses.

I can change wired mac address in LUCI, or appending:
option macaddr '00:24:89:41:4e:22'

and work as expected. But i cannot do that for wireless one, simply does not work.

Strange things, if i do:
ifconfig wlan0 down
ifconfig wlan hw ether 00:24:89:41:4e:22
ifconfig wlan0 up

MAC address change, but wireless does not work, i need to do a 'wifi restart', and after that MAC address get back to 'wrong' one.

I've tried to look for that in OpenWRT wiki, also in b43 driver page, but nothing useful popoup.

Thanks.
