Follow-up Comment #19, patch #6370 (project lwip):

There are. :-[

We are forwarding at the IP level, so we don't prepend any link-level header.
But netif->input() (ethernet_input() for me) requires such a header.

I think netif_poll() should forward up this way:
-      if(netif->input(in, netif) != ERR_OK) {
+      if(ip_input(in, netif) != ERR_OK) {

The same should be in netif_loop_output() (see attached patch) but I have no
threads so I didn't test that.
