Nothing. DHCPv6 uses the concept of DUID (Device Unique Identifier)
to identify an endpoint. This DUID _may_ be constructed from a MAC
address, but there are other options. See
http://tools.ietf.org/html/rfc3315#section-9 - specifically you're
expecting DUID-LL (chapter 9.4).

In the DOCSIS world, operators ask the CPE vendors to use MAC address
for DUID construction in order to be able to correlate DHCPv4 and DHCPv6
identities.

I can't follow?!
