pcap DLT request for virtio-scsi SCSI transport

[Stefan Hajnoczi <stefanha () gmail com>]

The QEMU system emulator now supports the virtio-scsi SCSI transport
for efficient virtualized SCSI I/O.  I would like to support
virtio-scsi debugging and analysis with pcap.

The pcap data will include the virtio buffers containing SCSI command
metadata, CDB, and data-out buffer.  A similar structure is also used
for SCSI responses with the data-in buffer and a footer.

You can find detailed information on virtio-scsi in Appendix H of the
virtio specification:
http://ozlabs.org/~rusty/virtio-spec/virtio-0.9.4.pdf

Is it possible to allocate a datalink type for virtio-scsi?

Do you need a detailed specification of the virtio-scsi pcap mapping
or should we publish the specification ourselves to enable others to
easily read such files?

Thank you,
Stefan
