Changelog:
Mike Cruse : mcruse@cti-ltd.com
- : Changes for Linux 2.0 compatibility.
+ : Changes for Linux 2.0 compatibility.
: Added dev_id parameter in net_interrupt(),
: request_irq() and free_irq(). Just NULL for now.
Mike Cruse : Added MOD_INC_USE_COUNT and MOD_DEC_USE_COUNT macros
: in net_open() and net_close() so kerneld would know
- : that the module is in use and wouldn't eject the
+ : that the module is in use and wouldn't eject the
: driver prematurely.
Mike Cruse : Rewrote init_module() and cleanup_module using 8390.c
: as an example. Disabled autoprobing in init_module(),
: not a good thing to do to other devices while Linux
: is running from all accounts.

Alan Cox : Removed 1.2 support, added 2.1 extra counters.

Split this off into mac89x0.c, and gutted it of all parts which are
not relevant to the existing CS8900 cards on the Macintosh
(i.e. basically the Daynaport CS and LC cards). To be precise:
or override something. */
