Depends on the SCSI bus type. CDBs without transport information do
not provide enough information for SCSI transports supporting I/O
depth > 1. As far as I know the only SCSI transport type currently
supported by Wireshark is iSCSI. The first step when adding support
for another SCSI transport would be to define a new libpcap link-layer
header type. See also http://www.tcpdump.org/linktypes.html.
