OK, I've added LINKTYPE_INFINIBAND and DLT_INFINIBAND, with a value of 247. The list of link-layer header types at http://www.tcpdump.org/linktypes.html should update in 24 hours or so; the description is "Raw InfiniBand frames, starting with the Local Routing Header, as specified in Chapter 5 "Data packet format" of InfiniBand™ Architectural Specification Release 1.2.1 Volume 1 - General Specifications.", with "InfiniBand™ Architectural Specification Release 1.2.1 Volume 1 - General Specifications" linking to the URL you gave. _______________________________________________ tcpdump-workers mailing list tcpdump-workers@lists.tcpdump.org https://lists.sandelman.ca/mailman/listinfo/tcpdump-workers
