Some time ago it had been assumed, that no more than 1 network interface
is supported. I remember having considered multiple network interfaces
in early development stages. And indeed, I tested this about a year ago
with an Ethernet to GPRS gateway and it worked out of the box.

I missed to update this wiki page.

However, assigning multiple IP addresses to a single interface could be
a real problem, because in the initial design this was not in my mind.

Is there really any need to assign multiple IP addresses to an embedded
system's network interface?
