I get low throughput with DB1200 also, although I did not measure
it (yet). I noticed very slow NFS mounted rootfs and I get a lot of:
NFS server not responding, still trying
NFS server O.K.
(Something like that, I do not have the board here right now).

AMD supplies smc9111 driver in smc9111.c/h. Should I use
this driver or is smc9x.c/h better?

BR,
