2 * INET An implementation of the TCP/IP protocol suite for the LINUX
3 * operating system. INET is implemented using the BSD Socket
4 * interface as the means of communication with the user level.
5 *
6 * Global definitions for the ANSI FDDI interface.
7 *
8 * Version: @(#)if_fddi.h 1.0.2 Sep 29 2004

10 * Author: Lawrence V. Stefani, <stefani@lkg.dec.com>
11 *
12 * if_fddi.h is based on previous if_ether.h and if_tr.h work by
13 * Fred N. van Kempen, <waltje@uWalt.NL.Mugnet.ORG>
