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.
 
HISTORY
 The tr driver appeared in NetBSD 1.4.
BUGS
 The PCMCIA attachment does not work with the 
cbb(4) CardBus driver.
