/*
 * FDDI support for tcpdump, by Jeffrey Mogul [DECWRL], June 1992
 *
 * Based in part on code by Van Jacobson, which bears this note:
 *
 * NOTE:  This is a very preliminary hack for FDDI support.
 * There are all sorts of wired in constants & nothing (yet)
 * to print SMT packets as anything other than hex dumps.
 * Most of the necessary changes are waiting on my redoing
 * the "header" that a kernel fddi driver supplies to bpf:  I
 * want it to look like one byte of 'direction' (0 or 1
 * depending on whether the packet was inbound or outbound),
 * two bytes of system/driver dependent data (anything an
 * implementor thinks would be useful to filter on and/or
 * save per-packet, then the real 21-byte FDDI header.
 * Steve McCanne & I have also talked about adding the
 * 'direction' byte to all bpf headers (e.g., in the two
 * bytes of padding on an ethernet header).  It's not clear
 * we could do this in a backwards compatible way & we hate
 * the idea of an incompatible bpf change.  Discussions are
 * proceeding.
 *
 * Also, to really support FDDI (and better support 802.2
 * over ethernet) we really need to re-think the rather simple
 * minded assumptions about fixed length & fixed format link
 * level headers made in gencode.c.  One day...
 *
