I'd like to get information on how much of the mmap'ed ring buffer is being used so that I can deal with dropped packets more effectively. Iwas going to add a patch for this, but its not clear to me the best wayto expose the information. I'm tempted to just add an additional call/struct for the information, but it would be nice if the existing API's could be extended instead.
What existing API were you thinking of extending? Note that you can't grow the pcap_stat structure without breaking binary compatibility.
