[PATCH net v2 10/15] drivers: net: cirrus: mac89x0: Remove this driver

Andrew Lunn
2026-04-22T18:27:38Z

The mac89x0 was written by Russell Nelson in 1996. It is an MAC
device, so unlikely to be used with modern kernels.

This is a driver for the ethernet hardware included in EP93xx CPUs.
Say Y if you are building a kernel for EP93xx based devices.

-config MAC89x0

- Support for CS89x0 chipset based Ethernet cards. If you have a
- Nubus or LC-PDS network (Ethernet) card of this type, say Y here.

- To compile this driver as a module, choose M here. This module will
- be called mac89x0.

-
- 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()
