=RFC 4638 Information=
When using a router with an external modem, one has to use PPPoE on the router as the connection method. This normally means that the MTU on the PPPoE link
can be no higher than 1492 octets (PPPoE has an 8 octet overhead, and the whole packets has to fit in a 1500 octet Ethernet frame). However, there is a
technique to use ''baby jumbo frames'' to extend the Ethernet frame size to 1508 octets and allow the full 1500 octets on the PPPoE link.
