So let's assume I'm a DHCPv6 server, and I receive the following three
Solicit messages (all from the same client since they have the same
DUID):

1. (DUID1, IAID2)
2. (DUID1, IAID3)
3. (DUID1, IAID4)

Furthermore, assume the two first Solicit messages are sent through
Ethernet interface 1, and the last Solicit message is sent through
Ethernet interface 2.

How can the server differentiate the client interfaces?
