is there anyone out there successfully using the SMC 91C111 ethernet

I had similar issues with smc91x.c on a different platform,
where the bus it is connected to was rather slow (and no DMA)
-> dropped packets.
Try to use NFS via TCP, or force a 10Mbit connection
with ethtool or by hacking the driver (ctl_rspeed).
(For me tcp works.)
