- * Fixes:       3 Feb 97 Paul Norton <pnorton@cts.com> Minor routing fixes.
- *              Added rif table to /proc/net/tr_rif and rif timeout to
- *              /proc/sys/net/token-ring/rif_timeout.
- *              22 Jun 98 Paul Norton <p.norton@computer.org> Rearranged
- *              tr_header and tr_type_trans to handle passing IPX SNAP and
- *              802.2 through the correct layers. Eliminated tr_reformat.
