Eventually, we'll be using this format to debug multi-path TCP, in which case the IP addresses (and maybe even the IP4/IP6-ness of it) might change. And gzip'ed those addresses will compress quite easily.
OK, so I'll stick with the simplicity of just repeating it for every frame then. -- Paul "LeoNerd" Evans leonerd () leonerd org uk http://www.leonerd.org.uk/ | https://metacpan.org/author/PEVANS _______________________________________________ tcpdump-workers mailing list tcpdump-workers () lists tcpdump org https://lists.sandelman.ca/mailman/listinfo/tcpdump-workers
