    Subject[049/264] usbmon vs. tcpdump: fix dropped packet count
    3.1-stable review patch.  If anyone has any objections, please let me know.

    ------------------

    From: Johannes Stezenbach <js@sig21.net>

    commit 236c448cb6e7f82096101e1ace4b77f8b38f82c8 upstream.

    Report the number of dropped packets instead of zero
    when using the binary usbmon interface with tcpdump.

    # tcpdump -i usbmon1 -w dump
    tcpdump: listening on usbmon1, link-type USB_LINUX_MMAPPED (USB with padded Linux header), capture size 65535 bytes
    ^C2155 packets captured
    2155 packets received by filter
    1019 packets dropped by kernel
