It seems PACKET_MMAP was added to the main libpcap distribution in January 2008: http://github.com/mcr/libpcap/commit/92c5d33d7a89c624e90b55f95bb7fbc49ec06c5f

(I have no evidence that it does; in fact, I'm a bit unsure how to check whether tcpdump is using mmap or not) -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
