+ * 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...
