Hi all
there is a limit to the number of sockets in a pf_ring kernel cluster,
it used to be 32, now I increased it to 64 which I guess should be enough.

For example, rings less than 32, I send 400000 packets to server and pf_ring info in /proc shows there is 400000 packets in rings, but when rings greater than 32, I can get 800000 packets when 33 rings and 1200000 packets when 34 rings and so on.
