I see. Then devices.h seems correct. I was wondering about NEED_CPU stuff.

Maybe you could add it as an ISA device to PC (pc.c) and see if it works?

Just add a line like
qemu_register_reset(dm9000_hard_reset, state);
to dm9000_init().

Then if the machine gets reset by monitor command "system_reset" or a
hardware device,  the reset function will be called to make the device
state predictable like on a real machine.
