Library? What kind of a library? I don't think it's a complete stack.
It's just a hardware library for the included ethernet controller (init,
send,...) and no TCP/IP Stack. Are there a documentation for lwIP, which
shows the needed modifications to port the lwIP-Stack to other hardware
systems? Or a list of files which must be modify?
I think things you mention in your next paragraph should be enough.

FreeRTOS supplies sys_arch functions for threading support.(I
think this is the recommended way in lwIP) If you go for ST you have to
implement your own sys_arch functions.

There is a ported freertos for the STR912. So i don't need to implement own
sys_arch functions, or? I "just" have to port the lwIP-Stack ethernet
Interface for the STR9. Because the sys_arch functions, which lwIP use, are
freertos functions(when i use the ARM7 freertos/lwIP example on
www.freertos.org).
So i combine the STR9 freertos with the lwIP/freertos-port (with adapted
hardware ethernet interface)?! Or is that a completely wrong way?
Sure,that's the way. Just modifing FreeRTOS sys arch functions according
to your processor will be enough. In fact, since
FreeRTOS has a working port for STR912 it is not such a big deal.
Besides you can contact FreeRTOS maintainer(Richard Barry)
for help. I guess he will be happy to see a working copy of FreeRTOS +
lwIP on a ST.
