add DHCP options support
In france a lot of operators are providing a tripe play offer (Data, Video, VOIP) via their box and are more and more virtualising the network. My provider Orange is for example using raw IP + DHCP options and will soon stop to support PPPOE. The authentication work with rfc3442 classless routes in DHCP client.
It would be interresting to support such configuration so the router can eventually connect directly to the ONT.
