[−][src]Struct pnet_packet::gre::Gre
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.
