I had sent a mail yesterday describing the problems I was having when =
running a TCP client on the LwIP side and a TCP server side on Linux =
stack talking over a TAP/TUN interface.

I studied that problem some more. I think the latter problem (TCP =
enqueue failure) was because of the previous problem of ARP failure. =
When I ran tcpdump I noticed that the ARP packets sent by the LwIP side =
had bad addresses in it. When I traced the functions I noticed the =
comment in arp_query() function in arp.c saying "This is not =
implemented".

So is ARP request from the LwIP side not implemented? Is that the reason =
why I see bad addresses in the ARP request when I run tcpdump? Is there =
some way to make this work?

Thanks,

Rajaram
