Ethereal only shows what's available on the wire. There are a few
exceptions to that (timestamp, ATM info available in an ATM Sniffer trace,
etc.), but our capture library, libpcap, doesn't reach into the OS and
pull out protocol stack variables.

Integrating that information with a packet capture program is an interesting
idea, however.
