The wwan0 interface will allow any MAC address (the driver will often
use a random one), but the modem plays a few tricks with neigbour
discovery so I am not going to bet on *multiple* MAC addresses working
until it is tested.

Does bridging work, Thomas?  If so, then that would be my favourite
alternative as long as there is no DHCP-PD (and I guess there isn't?)
