This plugin implements a dissector for Infiniband. It is released under the GPL v2. Rather than using say libpcap to capture raw (unframed) IP packets from near the top of an IPoIB stack, this plugin dissects link level Infiniband frames. Infiniband trace files can be read from Endace ERF format trace files, or from libpcap DLT_ERF files containing ERF TYPE_INFINIBAND records. There is currently no native DLT_INFINIBAND in libpcap. Each record contains a hardware timestamp, capture metadata such as port Id, and a complete link level Infiniband frame starting from the Local Route Header. svn path=/trunk/; revision=24628
