Here is a proposed patch that allows one to control the bridge MAC address.
Instead of the bridge choosing the MAC address with the least numerical
value, this patch chooses the MAC address from the last slave interface that
was added to the bridge. This is important in an ISP environment where MAC
addresses are carefully filtered and controlled. For example, the DHCP server
on an interior ISP network has a host entry for each MAC address that it
recognizes. The default is to deny allocation of an address. This helps
ensure that unauthorized machines cannot gain access, even if they have
physical access to the network (as is the case with wireless).
