[lwip-users] ethernetif and moving to the future 1.3

[Hans . Forsstrom]

Hello,
I'm currently working on moving our
existing solution based on lwIP 1.2 to the future version 1.3 (I got a
snapshot from CVS that I use for the moment). I have a couple of questions
that I hope that you can help me with.

We have implemented an ethernetif interface
based on the skeleton in version 1.2, we have also updated our thread handling
for 1.3 so now we are using multthreading for the lwIP stack. I wanted
to verify the changes that we have to do, and see if I missed something.
For the moment, before I done all the changed mention below, the tcpip
thread stops working after 4-5 hours of usage. The time it take to test
this is the main reason for me wanting to verify my changes instead of
trying to verify it using our test cases.

1: If I understand everything correctly
we should use tcpip_input instead of ethernet_input for our ethnetif interface
(multithreaded).

2: The ethernetif implementation shouldn't
handle ARP frames from now on, this will be handled by tcpip_input (using
ethernet_input). If we specify the netif flag NETIF_FLAG_ETHARP.

3: netif_add, netif_set_default and
netif_set_up should be replaces with netifapi_netif_add, netifapi_netif_set_default
and netifapi_netif_set_up. We doesn't call this methods from the tcpip
thread.

4: The arp_timer functionality shouldn't
be part of ethernetif any more, this is now handled by the tcpip thread
instead.

Is this correct and does anyone see
something that I have missed?

Thanks for the help in advance!

Best Regards,
Hans Forsström
