The interface details code is still called directly from Wireshark.  I
was thinking of adding an option to dumpcap to print out the details as
a list of colon-separated fields, and simply reprint them in the details
window.  This would let us add detail fields to dumpcap at any time
without having to update the GTK code.  What do you think?
