From Onno van der Linden:
Reorganise the driver some what. Rename tr_reset() to the more appropriate tr_stop(). Create a common tropic reset routine and use it in the frontends. Move the code in tr_config() which is only used in the card attachment routines into a new tr_attach() function. Take adapter off the ring through tr_shutdown() in a shutdown hook. This simplifies the bus-specific frontend.

|

* From Onno van der Linden:
|
||||
* Reorganise the driver some what.
|
||||
* Rename tr_reset() to the more appropriate tr_stop().
|
||||
* Create a common tropic reset routine and use it in the frontends.
|
||||
* Move the code in tr_config() which is only used in the card attachment
|
||||
* routines into a new tr_attach() function.
|
||||
* Take adapter off the ring through tr_shutdown() in a shutdown hook.
|
||||
* This simplifies the bus-specific frontend.
|
||||
*
|
||||
* Revision 1.2 1999/03/22 23:01:36 bad
|
||||
* Oops. RcsID police.
