In linux kernel since version 2.6.12  
This driver provides generic support for token ring adapters
based on the Texas Instruments TMS380 series chipsets. This
includes the SysKonnect TR4/16(+) ISA (SK-4190), SysKonnect
TR4/16(+) PCI (SK-4590), SysKonnect TR4/16 PCI (SK-4591),
Compaq 4/16 PCI, Thomas-Conrad TC4048 4/16 PCI, and several
Madge adapters. If you say Y here, you will be asked to select
which cards to support below. If you're using modules, each
class of card will be supported by a separate module.

If you have such an adapter and would like to use it, say Y and
read the Token-Ring mini-HOWTO, available from

Also read the file Documentation/networking/tms380tr.txt or
check <>.

To compile this driver as a module, choose M here: the module will be
called tms380tr.
