If it's not using PF_RING because of the variable, any idea on how to
disable the variable?

I grep'd through the sources looking for that string, in hopes to remove
that line, it seems to only be present in the binary.

I'm not sure how you would pass the option to disable it through configure.

I tried --disable-FEATURE=PCAP_NO_PF_RING
and --disable-PCAP_NO_PF_RING

Any ideas?
