Header of a PPP packet.

A PPP packet is transmitted as a payload of an HDLC packet. PPP packets only carry information about control protocol of a PPP stack (Link Control Protocol, IP Control Protocol, etc). IP packets encapsulated in HDLC frame are not considered PPP packet.

The format of PPP header plus payload is:

0 1 2 3 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | Code | Identifier | Length | +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | Payload ... +-+-+-+-+
