First of all I applied patches 1-4 to next.

I can't get this version to work. I have done:

# eth0.ethaddr=00:04:9f:01:b5:37
# eth0.ipaddr=192.168.23.170
# eth0.netmask=255.255.0.0
# mount -t tftp 192.168.23.4 /mnt/
# cp mnt/b b
T T T T could not open mnt/b: Interrupted system call
# picoping 192.168.23.4
 ---- Ping timeout!!!
PING 1 to 192.168.23.4: Error 1
picoping: I/O error

Anything I have missed?

I noticed that the MAC address is no longer set and the stack no longer
checks for a link. I believe picotcp should call eth_send rather than
invoking eth->send directly.

Sascha
