NAME
     tr -- TROPIC based shared memory Token-Ring cards device driver

SYNOPSIS
     tr0 at isa? port 0xa20 iomem 0xd800 irq ?
     tr* at isa? port ? irq ?
     tr* at isapnp?
     tr* at mca? slot ?
     tr* at pcmcia? function ?

DESCRIPTION
     The tr device driver supports TROPIC I based shared-memory Token-Ring
     cards.

HARDWARE
     Supported cards include the following IBM and 3Com models:

           IBM   Token-Ring Network PC Adapter

           IBM   Token-Ring Network PC Adapter II

           IBM   Token-Ring Network Adapter/A

           IBM   Token-Ring Network 16/4 Adapter

           IBM   Token-Ring Network 16/4 Adapter/A

           IBM   Token-Ring 16/4 Credit Card Adapter

           IBM   Token Ring Auto 16/4 Credit Card Adapter

           IBM   Turbo 16/4 Token Ring PC Card

           IBM   16/4 ISA Adapter

           IBM   Auto 16/4 Token-Ring ISA Adapter

           IBM   Token Ring 16/4 Credit Card Adapter

           IBM   Token Ring Auto 16/4 Credit Card Adapter

           IBM   Turbo 16/4 Token Ring PC Card

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

HISTORY
     The tr driver appeared in NetBSD 1.4.

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