Seems good enough to me. Is there a stable reference in the wireshark tree/doc/etc. I can point to? How does this sound: /* * DLT type for upper-protocol layer PDU saves from wireshark. * * the actual contents are determined by two TAGs stored with each * packet: * EXP_PDU_TAG_LINKTYPE the link type (DLT value) of the * original packet. * * EXP_PDU_TAG_PROTO_NAME the name of the wireshark dissector * that can make sense of the data stored. */ #define DLT_WIRESHARK_UPPER_PDU 252 Code should be on github in... there: https://github.com/the-tcpdump-group/libpcap/commit/e65639c26a00397703102861466473c24181b47c please fork/edit with more info, and let us know how it works. -- ] Never tell me the odds! | ipv6 mesh networks [ ] Michael Richardson, Sandelman Software Works | network architect [ ] mcr () sandelman ca http://www.sandelman.ca/ | ruby on rails [ _______________________________________________ tcpdump-workers mailing list tcpdump-workers () lists tcpdump org https://lists.sandelman.ca/mailman/listinfo/tcpdump-workers
