Ethereal does not know anything about the low-level part of capturing on
network interfaces; it relies on the libpcap library to handle all of
that, and libpcap relies on the underlying OS.

Unfortunately, Linux doesn't support treating FCP as a network protocol,
using its networking infrastructure - it supports IP-over-FC, but not
FCP, in that fashion - which means libpcap, and thus Ethereal, don't
support capturing FCP traffic in that fashion.
