### 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

ifmedia(4), intro(4), isa(4), isapnp(4), mca(4), pcmcia(4), ifconfig(8)

### HISTORY

The tr driver appeared in NetBSD1.4.

### BUGS

The PCMCIA attachment does not work with the cbb(4) CardBus driver.
