bluetooth spec v1.1 does not define a way to set device's bd_addr.

i guess it *might* be possible via vendor specific command. of course
you would need to know the vendor command opcode and the parameters
for the specific bluetooth chip. good luck finding them out. vendor
commands on some chips do not even return any events back, so it makes
it hard to just probe all possible opcodes to see what device does.

device's bd_addr is the only way to identify bluetooth device. you are
not supposed to change it. everything else is tied to the bd_add, i.e.
security etc. why do you want to change it anyway?
