-  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()
