PS: one thing which took unexpected time in the SD-NAT demo at the IETF
meeting on Sunday was the fact the LL DUID of CPE boxes didn't contain
the MAC address of the Ethernet uplink (the one printed on the box,
or returned by ifconfig / ip addr) but the previous (value - 1) one...
BTW I believe it shouldn't have been too surprising: it is one of the
reasons the idea to pickup the MAC address in LL or LLT DUIDs doesn't
work.
