--
The Fibre Channel protocol defines a virtual fabric tag (VFT) similar to
ethernet's VLAN tag.  It is sometimes called the VSAN tag.  
It used to be proprietary, but now it's standard.
Wireshark currently displays it as an 8-byte field without dissecting it
further.
It'd be nice to have it broken down into fields.
A patch is attached.
