GRE (Generic Routing Encapsulation) Packet.

See RFCs 1701, 2784, 2890, 7676, 2637

Current status of implementation:

  • RFC 1701 except for source routing and checksums. Processing a source routed packet will panic. Checksums are able to be inspected, but not calculated or verified.

  • RFC 2784 except for checksums (same as 1701 status). Note that it is possible to generate noncompliant packets by setting any of the reserved bits (but see 2890).

  • RFC 2890 implemented

  • RFC 7676 has no packet changes - compliance is up to the user

  • RFC 2637 not implemented.

Note that routing information from RFC 1701 is not implemented, packets with routing_present true will currently cause a panic.
