That'll be the non-PF_RING enabled driver. You probably need to do
"rmmod e1000e;modprobe e1000e" to get the 1.0.15 driver. PF_RING will
work without, it just won't be as much of a performance boost.

pcount uses libpcap; what does pfcount (native PF_RING) do? If you're
feeling brave you can try "transparent_mode=2" in pf_ring, but make sure
you're not using the same interface for non-PF_RING apps like SSH :)

Best Wishes,
