The packet formats for extcap are pcap format: https://ietf-opsawg-wg.github.io/draft-ietf-opsawg-pcap/draft-ietf-opsawg-pcap.html and pcapng format: https://ietf-opsawg-wg.github.io/draft-ietf-opsawg-pcap/draft-ietf-opsawg-pcapng.html and the link-layer types in those file formats are as described in https://www.tcpdump.org/linktypes.html That page lists both: LINKTYPE_CAN20B, for which the format is *not* defined (I asked the people who requested it, and they don't have any documentation available); LINKTYPE_CAN_SOCKETCAN, which is described at https://www.tcpdump.org/linktypes/LINKTYPE_CAN_SOCKETCAN.html. That page will soon be updated to describe how CAN XL frames are handled. ___________________________________________________________________________ Sent via: Wireshark-dev mailing list <wireshark-dev@wireshark.org> Archives: https://www.wireshark.org/lists/wireshark-dev Unsubscribe: https://www.wireshark.org/mailman/options/wireshark-dev mailto:wireshark-dev-requ...@wireshark.org?subject=unsubscribe
