# SOURCE ROUTING

Setting IFF_LINK0 enables Token-Ring source routing. Setting IFF_LINK1 uses all-routes broadcasts otherwise single-route broadcasts are used.

# NOTES

The MCA attachment has been only tested on IBM Token Ring 16/4 Adapter/A so far. It doesn't support ifmedia(4) yet, too.

# SEE ALSO

# HISTORY

The `tr` driver appeared in NetBSD 1.4.

# BUGS
