Ethernet protocols.

pp_proto ppf proto pretty-prints the ethernet protocol proto on ppf.

The type of an Ethernet packet.

sizeof_ethernet is the byte size of the ethernet header.

of_cstruct buffer attempts to decode the buffer as ethernet packet. It may result an error if the buffer is too small, or the protocol is not supported.

into_cstruct t cs attempts to encode the ethernet packet t into the buffer cs (at offset 0). This may fail if the buffer is not big enough.

make_cstruct t encodes the ethernet packet t into a freshly allocated buffer.
