Just wanted to update the list that I quit spending cycles on this and for the time being reverted back to running our clusters with the non-commercial version of pf_ring.

I can only comment on my experience, but I discovered there is an extreme lack of quality documentation and the "commercial support" that came with the 10 licenses was nearly non-existent.

Lessons have been learned and when the need to expand comes we'll be looking at other commercial solutions to replace our X520's with.

I have NTop's PF_RING and ixgbe driver packages installed, the proper license in /etc/pf_ring, and have compiled Bro with the NTop libraries but I'm seeing the kernel error below along with a ton of “split routing” messages in weird.conf, so I suspect the flows aren’t being load balanced correctly.
