Hello, Luca! I'm loading ixgbe patched ixgbe driver, loaded pf_ring, start hping flood from another machine and got 90% of kernel load from ksoftirqd. I did not started any toolkit yet :(
But ZC looks like working because it work many times faster then vanilla PF_RING and process 2 mpps of packets! And it complains about license: # ERROR: You do not seem to have a valid PF_RING ZC license 6.0.2.140923 for eth4 [Intel 10 Gbit ixgbe 82599-based] # ERROR: Please get one at http://shop.ntop.org/.
