Hi Alfredo

Downloaded latest code from SVN (rev 8711), and installed PF_RING (make and 
make install in folders PF_RING/kernel, PF_RING /userland/lib, 
PF_RING/userland/libpcap and 
PF_RING/drivers/ZC/intel/ixgbe/ixgbe-3.22.3-zc/src).
But ./load_driver in PF_RING/drivers/ZC/intel/ixgbe/ixgbe-3.22.3-zc/src results 
in error:
root@liproxy:/opt/PF_RING/drivers/ZC/intel/ixgbe/ixgbe-3.22.3-zc/src#<mailto:root@liproxy:/opt/PF_RING/drivers/ZC/intel/ixgbe/ixgbe-3.22.3-zc/src#>
 ./load_driver.sh
Error: Module ixgbe is not currently loaded
Error: could not insert module ./ixgbe.ko: Unknown symbol in module

Hi

Can you please answer my questions regarding using ZC with libpcap?
Using "-i zc:eth2" in tshark or in our application that uses PF_RING aware 
libpcap via jnetpcap does not return any packets.

Thank you,
Katarina Valent
