Hello Michal,

I guess I didn’t explain the question very well.

I have a machine with 2 cards: A quad I350 Intel card, and a dual Endance card. Currently I have several 1Gb copper connections to the Intel card, which is setup with Suricata via PF_RING. I’m planning to connect the DAG to a 10Gb fiber feed. I’m wondering if the same Suricata instance can handle input from both simultaneously (still using PF_RING for the Intel card, but using DAG for the Endace card).
