Simon,

I'm work in full time on lwIP these days, and I can do it now. I can already commit :

ethernetif.c.patch
tcpip.c.patch

and the solution I propose you in the forum (with the "low-level" filter).

Finally, all that is the same problem :

"small change in tcp/ip initialization"
"the ARP layer is not protected againstconcurrent access"
"Faulty arp initialization in ethernetif_init skeleton" and even
"Option to allow etharp to update from IP packets"

Are you agree I commit it in CVS ?

[See lwip-users posts with the same subject]

It is planned to move ARP processing into tcpip_thread() if using multithreaded environment, so that ARP layer is accessed only from one thread (like the rest of the lwIP core).

I'm on it, give me some days ;-)
