> - Changelog:
> -
> - Mike Cruse : mcruse@cti-ltd.com
> - : 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@debian.org>
> -
> - 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@conectiva.com.br> - 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()
