Dear Luca,
I've updated my kernel 2.6.22.3 with PF_RING rev 3295 and now I have good
news: Work Fine! Take a look:
192.168.0.5 = My desktop
192.168.0.121 = Debian Etch - linux 2.6.22.3 pfring support.

I have also tested PF_RING rev 3295 against the lastest kernel 2.6.22.6 and
work fine too.
What was the problem?
Cheers,
