usbmon vs. tcpdump: fix dropped packet count
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 Signed-off-by: Johannes Stezenbach <js@sig21.net> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
