First off, Alfredo thanks for answering all my questions as I get up to
speed on PF_RING.
I have a few other questions based off of some /proc/net/pf_ring/ output.
1. In the first cat I have 0 free slots and the second 13k, am I dropping
traffic when there aren't free slots? Should I increase the slots even more?
2. Why do I have lost packets? I have some rings with 0% and others with
about 5% packet drops. Is this normal?
3. My capture mode is set for RX only in the info file, but the ring file
says both?
4. Is socket mode something I should worry about?
Thanks,
