Re: Problem with TCP/IP stack
Sorry for the preceding message that was not send to the list, little
mistake from me (cliqued "reply" and not "reply to all").
Yes my application print about DHCP transaction and it is ok. I have
added some prints in every driver function in order to trace what it
is doing. The output is interesting :
1) The NIC is making interrupts all the time
2) The network stack never call the send() function.
Here is the output :

Network initalized !

It seem that everthing is OK. start sending packets.
