2.4.9-pre13aa1 & 2.4.9-pre14: SMP + 3c59x: feature/bug?

2.4.9-pre13aa1 & 2.4.9-pre14: SMP + 3c59x: feature/bug?

[Mario Vanoni]

Dual SMP PIII550 BX400 1024MB mem
according "Documentation/Changes" all >= update.

Both kernels compiled *_without_* modules:
lilo.conf with append="ether=0,0,3,eth0".
Ethernet doesn't work anymore,
with 2.2.19pre#aa#, 2.2.20pre#aa# perfect.

Both kernels compiled with 3c59x as module:
modules.conf:
alias eth0 3c59x
options 3c59x options=3
obviously without append in lilo.conf.
Ethernet works as usual.

No difference on all other application.

Net drivers which use the new alloc_etherdev API do not
support the `ether=' kernel boot option.

Going back to the old init_etherdev() API will make it
work again.

Does not work, patched against 2.4.9-pre14aa1.

Returned (grin ...) ... to modules.

2.4.10: 3c59x: buggy?

[Mario Vanoni]

2.4.10 works on a SMP and an UP perfectly,
except the ethernet with 3C905 COMBO.

UP:  works with or without enabled modules.

SMP: works _only_ with modularized kernel,
     only needed module: 3c59x.
