Hello, all and Thomas especially! :)
The last time Thomas's help was so effective, that I hope he knows the
decision of my (I hope the last) today's problem:
Using netdemo application I send UDP packets to the Linux box with nc -lu
waiting. I press 'u' in console and it starts sending UDP packets.
Everything works fine, but approximately once per 7-10 restarts I see that the
very first packet does not arrive!
I put counter into the packets and can see its '0' value is missed rarely
I run tcpdump to check and also saw when this occurs, that the first packet is
missed in the tcpdump too.
What can it be and how can I debug the situation?
[Each time I put breakpoint in the driver at buffer sending the problem never
occurs.:( But there are other packets too...]
Thanks a lot ahead.
