there're some onu in the wild, which insert opt82 in relayed requests and drop any unmatching replies (w/o same opt82).
to fix that, need to improve dhcp compliance for following rc3046 parts:
2.1 Agent Operation
The Relay Agent Information option echoed by a server MUST be removed
by either the relay agent or the trusted downstream network element
which added it when forwarding a server-to-client response back to
the client.
2.2 Server Operation
DHCP servers claiming to support the Relay Agent Information option
SHALL echo the entire contents of the Relay Agent Information option
in all replies. Servers SHOULD copy the Relay Agent Information
option as the last DHCP option in the response.
