Well, problem is something more complicated... At least for me :)

NUM_ETH_INTERFACES is defined /include/asm-mips/mach-au1x00/au1000.h
for all machines (au1000 au1100 au1500 au1550) except au1200. I dont
think that someone forgot to add NUM_ETH_INTERFACES for au1200. And
even what it means? All these machines have "on-board" ethernet
controller in processor core, so I think there's no external chip on
development board. au1200 haven't internal controller and has
dedicated chip on board...

 Furtermore, I found now, that Linux 2.4.26 distributed by AMD has an
additional option CONFIG_AU1XXX_SMC91111 in config for DBAu1200 which
controls compiling drivers/net/smc91111.c.
 In 2.6 this file disappeared but we have drivers/net/smc91x.c which
configures in some arm, ppc, and superh architectures. MIPS knows
nothing about him. Is it the right file? I suppose it is, but...

 Am I first who put 2.6 kernel on this board and see that is there no
drivers for it ? :)
