=> in fact you can't: there is no direct way to carry the hardware address
in DHCPv6. BTW the opposite exists: RFC 4361 specifies a way to use
a DUID in DHCPv4. Of course you can find it in DHCPv6 messages, the problem
is usually there are many ways which are not guaranted to return a value
or the same value.
See 'MAC/Hardware Addresses in DHCPv6' section in the ARM...
