I've obtained some pcaps from both ends and I can see the following changes occurring to a DHCP Request:

1) The transaction ID is changed
2) Option 82 is added. More specifically, sub-option 1 Agent Circuit ID is present and has a valid length. sub-option 2 Agent Remote ID is present, has a length of 0 and no content which wireshark doesn't seem to like much.
