Hello there. I have recently upgraded a machine (amd64) running 10.2-STABLE (r286771) to revision r287298. After that I could no longer run tcpdump on the interfaces (fails with 'pcap_loop: BIOCROTZBUF: Capabilities insufficient'), or neither could I use pflogd (eats cpu) unless I set sysctl net.bpf.zero_copy=0. Had that set to '1' earlier, and everything was fine. Something changed recently? Thanks a lot, Emre.
