It is not necessary for PF_RING to use different cluster id per capture interface.

You can increase the the number of works per cluster id by changing CLUSTER_LEN linux/pf_ring.h from 8 to 16 or 32. 

There seems other limitation in the number of works on host in bro whne you gove above 8 works on a hosts.

Subject: [Bro] Bro and PF_RING Cluster ID

Hi all,

I'm running a clustered Bro instance with workers capturing traffic on three PF_RING enabled e1000e interfaces.

While looking in /proc/net/pf_ring/ I noticed that all of my Bro workers belong to cluster id 21. Is it possible (or desirable) in Bro to create a PF_RING cluster id per capture interface?

I read that PF_RING allows a maximum of eight workers per cluster id, is this still true?
