3Com
    3C619 TokenLink

3Com
    3C319 TokenLink Velocity

3Com
    3C389 TokenLink Velocity PC Card

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
