Hello all,


after extensive code analysis, I come to the conclusion that the ARP queueing could clash with the TCP queueing only when multiple packets are queued on a single ARP entry.

(The reason is that the packets are queued through their next pointer into a packet queue, thus modifying the single TCP segment pbuf chain. --- TCP code knows nothing about
pbuf packet queues).

I have disabled multi-packet queueing in etharp.c and everything should now work again.

Your test feedback is appreciated!

Regards,

Leon.
