Re: [lwip-users] Problem with do_writemore() + LWIP for AVR32

[address@hidden]

That file is written by ATMEL? I would have expected them to be able to 
read our example driver file... However, it seems like they have done it 
as they thought it has to be without really checking it :-( See below.

The above line is where your problems come from. It should read:

if(ERR_OK != netif->input(p, netif))

With that, tcpip_input (which is what netif->input points to, since it 
was passed to netif_add()) is called instead of ethernet_input, which 
makes sure that packets are first passed into the correct thread before 
being processed.
