Hi Alfredo We are using PF_RING via jnetpcap that uses PF_RING aware libpcap. How to enable ZC when using PF_RING in this way?

Do you have any instructions how to link pf_ring aware libpcap? Seems that we are using it wrong.

Now we are trying to upgrade existing system to use Intel 10G 82599 card and PF_RING ZC. Using instructions from https://svn.ntop.org/svn/ntop/trunk/PF_RING/userland/examples_zc/README.quickstartwe have installed ZC ixgbe driver and PF_RING. Additionaly, we have copied libpcap from PF_RING into usr/lib and linked it with libpcap.so.1 because we use jnetpcap and libpcap in our java application. Usage of example program zcount seems to be working fine, but we cannot se packets using tshark tool. Is there something extra we need to do to see these packets? Our fear is that if tshark doesn't see packets, our application also won't see them. Do we need to use some other JNI in our applicatio for it to work with PF_RING ZC?
