I've updated my PF_RING code and I'm not seeing any difference (i.e.,
pfcount -i eth2 still shows 0 packets received but ifconfig shows
packets being received). Here's what I'm seeing with the new version:
ifconfig eth2

I also tried pfcount -i dna:eth2, but got the following error:
pfring_open error (pf_ring not loaded or perhaps you use quick mode
and have already a socket bound to dna:eth2 ?)
but:

Any thoughts? Thanks for your help.
