We need it for our IPv6 Lab, were we want to implement the option 1026 from
the Docsis 3.0 specification. Our idea is that the relay agent is able to
read the option from an option field of the clients Solicite (e.g. from the
vendor specific information which is added with scapy to simulate different
CMs) and adds it to the Relay forward message. The advantage would be that
we can simulate various CMs to test our DHCP server in a practical way.
But for a first step it would be enough to add a static vendor specific
information as it is possible with the Remote ID.

Yes it would be possible to test your code.
