Hi Jarek.
Sorry for delayed answer. As I promised, I have started the tests on
Monday (in spite of dealing with The Monday Syndrome:)  I had applied
your patch and after two billions packet (and approximatly four hours)
passed kernel crashed with skb_over_panic error similar with first
type. To ensure the patch is failed or not, I rerun the same test
again. That time, surprisingly,  it did'nt crashed again for two days
with same kernel. But this situation had occured before, I think
sometimes because of randomness of the applied ethernet traffic and
mostly because I cant apply all full line rate random traffic to my
target device because of wrong test setup (switch / hardware packet
generator settings etc..), it takes three or more day to crash the
kernel and sometimes it never crashes. My device only and only crashes
when I can apply full line rate random traffic. Before informing you
and the list with (official) test results, I want to be sure with the
truth of them. So that please let me apply more test to the target
device for  a fews day more. After that I wish I'll came with good
news!
Thanks for your time and care alot.
Emin
