Thanks Kieran review the configuration.
It is GPRS environement, could only catpure sever log. It may not helpful.

Found the problem. Thanks to you and Kieran for the replies.
It's kind of a strange effect. So just in case anyone else runs into
a similar situation in the future, a quick description of what was
happening.
My driver is written so that when a new packet arrives or a
transmitted packet finishes

Yes. TCP_SND_BUF should cover all packets in flight from the

I think a compile time check would be a good id
Hi, i try to port lwip. I run the OS in qemu, and set lwip IP to 192.168.0.1
When i ping 192.168.0.1, i continuously get the following error, below.
Note : the qemu & tap0 setting was fine. Previous lwip port can be
ping-ed with this setting.
I also copy-paste my 'tcpdump -i tap0'.
Any idea ?
