Good question.  There's no effort in progress that I know of.
I find wireshark very handy and do tend to capture with tcpdump -w
and then read the file with wireshark.  tshark is handy if you
want a CLI mode.

If tcpdump interpreted FCoE frames, then we would want FC, FC-ELS,
and FCP.  Does it already dissect any SCSI frames (e.g., iSCSI)?
I'm not sure how much work it would be, but given tshark
is around, I don't think it's that important.

It could at least be changed to print out FCoE instead of 0x8906,
and FIP instead of 0x8914.
