Basically the driver got more picky and only allows the last 3 bit of
the MAC address changed. I just found out that if you generate your new
MAC accordingly it works!
I wonder wether this is addr_mask is necessary for all RT chipsets,
since mine (RT5372) happily accepted different MAC addresses before,
also in multi-AP configurations...
