> -  Mike Cruse        : mcruse@xxxxxxxxxxx
> -                    : 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
> -                    : 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.
> -
> -  David Huggins-Daines <dhd@xxxxxxxxxx>
> -
> -  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:
> -
> -    * Removed all the media-detection stuff, because these cards are
> -    TP-only.
> -
> -    * Lobotomized the ISA interrupt bogosity, because these cards use
> -    a hardwired NuBus interrupt and a magic ISAIRQ value in the card.
> -
> -    * Basically eliminated everything not relevant to getting the
> -    cards minimally functioning on the Macintosh.
> -
> -  I might add that these cards are badly designed even from the Mac
> -  standpoint, in that Dayna, in their infinite wisdom, used NuBus slot
> -  I/O space and NuBus interrupts for these cards, but neglected to
> -  provide anything even remotely resembling a NuBus ROM.  Therefore we
> -  have to probe for them in a brain-damaged ISA-like fashion.
> -
> -  Arnaldo Carvalho de Melo <acme@xxxxxxxxxxxxxxxx> - 11/01/2001
> -  check kmalloc and release the allocated memory on failure in
> -  mac89x0_probe and in init_module
> -  use local_irq_{save,restore}(flags) in net_get_stat, not just
> -  local_irq_{dis,en}able()
