net/ethernet: Move mac89x0.c from apple to cirrus
Macintosh CS89x0 based ethernet cards use a Crystal Semiconductor (Now Cirrus Logic) CS89x0 chip, so the mac89x0 driver should be in drivers/net/ethernet/cirrus instead of drivers/net/ethernet/apple. This also fixes a build problem, as the driver needs a header file from the cirrus directory: drivers/net/ethernet/apple/mac89x0.c:107:20: error: cs89x0.h: No such file or directory Signed-off-by: Geert Uytterhoeven <geert@linux-m68k.org> Signed-off-by: David S. Miller <davem@davemloft.net>

12 Changelog:
13
14 Mike Cruse : mcruse@cti-ltd.com
15 : Changes for Linux 2.0 compatibility.
16 : Added dev_id parameter in net_interrupt(),
17 : request_irq() and free_irq(). Just NULL for now.
18
19 Mike Cruse : Added MOD_INC_USE_COUNT and MOD_DEC_USE_COUNT macros
20 : in net_open() and net_close() so kerneld would know
21 : that the module is in use and wouldn't eject the
22 : driver prematurely.
23
24 Mike Cruse : Rewrote init_module() and cleanup_module using 8390.c
25 : as an example. Disabled autoprobing in init_module(),
26 : not a good thing to do to other devices while Linux
27 : is running from all accounts.
28
29 Alan Cox : Removed 1.2 support, added 2.1 extra counters.
30
31 David Huggins-Daines <dhd@debian.org>
32
33 Split this off into mac89x0.c, and gutted it of all parts which are
34 not relevant to the existing CS8900 cards on the Macintosh
35 (i.e. basically the Daynaport CS and LC cards). To be precise:
36
37 * Removed all the media-detection stuff, because these cards are
38 TP-only.
39
40 * Lobotomized the ISA interrupt bogosity, because these cards use
41 a hardwired NuBus interrupt and a magic ISAIRQ value in the card.
42
43 * Basically eliminated everything not relevant to getting the
44 cards minimally functioning on the Macintosh.
45
46 I might add that these cards are badly designed even from the Mac
47 standpoint, in that Dayna, in their infinite wisdom, used NuBus slot
48 I/O space and NuBus interrupts for these cards, but neglected to
49 provide anything even remotely resembling a NuBus ROM. Therefore we
50 have to probe for them in a brain-damaged ISA-like fashion.
51
52 Arnaldo Carvalho de Melo <acme@conectiva.com.br> - 11/01/2001
53 check kmalloc and release the allocated memory on failure in
54 mac89x0_probe and in init_module
55 use local_irq_{save,restore}(flags) in net_get_stat, not just
56 local_irq_{dis,en}able()
