Add support for Generic Framing Procedure. Generic Framing Procedure (GFP) is
used to map octet-aligned variable length payloads (e.g. Ethernet, MPLS,
octet-aligned PPP, IP) into octet-synchronous signals such as SONET/SDH (ITU-T
G.707) and OTN (ITU-T G.709). GFP is a telecommunications industry standard
defined in ITU-T G.7041/Y.1303. (https://www.itu.int/rec/T-REC-G.7041/)
Libpcap has long reserved link type for GFP (170 for Transparent mode, 171 for
Framed mode) and the patch will edit pcap-common and wtap to include support.
The attached file was produced by test equipment, so everything the encoded
Ethernet past the Ethernet addresses is the output of a PBRS and will look a
little odd. A third party tool with support for the reserved PCAP values for
GFP produced the pcap file, extracting it from the SONET/SDH that contained the
GFP.
