I have written a network driver that produces IP (I created both a convertor
and up producer in single driver). I get what appears to be a valid IP
packet (it is a echo reply to an echo request packet that I sent). And then
use tx_up() to put it into the stack. However, the ping application is not
ever seeing it. Is there some tracing I can perform inside io-net? How can
I see what is happening to the packet after tx_up()?
I am using tiny tcpip right now. I have examined the IP packet and it looks
good. The tx_up is returning 1 as expected. But I am getting a tx_done()
call for the packet before the tx_up() even returns. So, does this mean the
packet was rejected? How can I tell the reason?
Any ideas on how to determine what is happening to the packet?
we now have our code running on full tcpip and are getting the same problem.
now we are able to use netstat -ni and the output packets (we are pinging)
are working, just the ping replies are not. The Ipkts is always 0. I guess
this all means the echo reply packets are being discarded…

I was able to find the problem with the packet, but still am curious how I
am supposed to determine why the packet was discarded… In my case, I had
set a flag wrong…
