I'm interested to know if anyone has attempted to do mmaped capture with

memory-mapped capture on linux since 1.0.0:
Russ Combs recently suggested that snort has support for it in recent
I'm having trouble finding documentation or any evidence of folks using
this feature though. Does it require configuration to enable, or is it
automatic as long as the kernel, libpcap, and snort version all support
it? Is there a way to test and confirm that mmapped capture is being
used on a given snort instance?
