* 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...
