Read the PPPoE RFC. PPPoE adds 8 bytes of overhead to each packet. The typical Ethernet maximum frame size is 1500 bytes. If you knock of 20 bytes each for the IP and UDP headers, and 8 bytes of PPPoE overhead, your MTU is 1452. Larger packets will be fragmented if possible, or discarded if not. On some networks, you can increates the Ethernet maximum frame size, but this isn't always possible.
