Suricata

This may be a user issue, as I'm not very familiar with FreeBSD & netmap.

I'm running FreeBSD 10.3 with netmap on a 2 core system. So I would expect 2 worker threads.

netmap:
   # To specify OS endpoint add plus sign at the end (e.g. "eth0+")
 - interface: igb0
   # Number of receive threads. "auto" uses number of RSS queues on interface.
   threads: auto

I start with:

./src/suricata --netmap -v -l /tmp/ -c suricata.yaml

Immediately it starts giving this 'invalid polling request error':

AFAICS there should be 2 RSS queues:

If I set 'threads: 1' everything works.
