Yes, that is correct. > The Frame Header is 16 bits; do bits 15 through 8 appear in the first octet, > with bits 7 through 0 being in the second octet?

Yes I have added bit counting policy and byte order to the spec: https://bugs.wireshark.org/bugzilla/attachment.cgi?id=14267 _______________________________________________ tcpdump-workers mailing list tcpdump-workers@lists.tcpdump.org https://lists.sandelman.ca/mailman/listinfo/tcpdump-workers
