Hi Peter
it seems ixgbe is loaded while you should use ixgbe_zc, please let me
see the output of the following commands to double-check:
ethtool -i eth2
cat /proc/net/pf_ring/dev/eth2/info
It is recommended to use our init script installing packages from our
repository http://www.ntop.org/packages/. Please have a look at
http://www.ntop.org/wp-content/uploads/2011/08/n2disk-UsersGuide1.pdf Appendix
A - Configuring a PF_RING Deb/RPM package.

Hi,
I have pf_ring 6.1.1, for first step i try use this as very fast
packets generator. I have license for one mac (eth2). Something goes
wrong because doesn't use zero copy mode, don't see zc:eth2 device
I try this:
insmod /usr/src/pfring-6.1.1/pf_ring.ko transparent_mode=2
rmmod ixgbe
modprobe ixgbe_zc
centos 6 still use old driver ixgbe ??
lspci -v show me:
