You've missed etharp_init(); Also configure your interface
with either DHCP or a manual address
                               
netif_set_ipaddr(ethif, &ip);
netif_set_netmask(ethif, &nm);
netif_set_gw(ethif, &gw);
netif_set_up(ethif);

or 

dhcp_start(ethif);

You can create this easily based upon the default opt.h file.
Overrule your local defaults in your lwipopts.h.

I think your c16x port does not match the lwip release you've got.
This was changed some time ago. The contrib maintainers sometimes
forget to tag their stuff with the lwip release.

If you can use anonymous CVS and make a checkout of contrib/c16x
on the date the lwip version was released your problem is most likely
solved. (You can then use HEAD (the bleeding edge: not in the *.tar.gz
files) as well).

If you really really can't do this ask me for a recent checkout.

This is because your header and c version do not match.
Same problem again.

Hmm. Try using the EDE grep to find out  where these
definitions hang out.
