dissector: display packet direction for tap'ing on netlink devices (nlmon)
Linux kernel provides nlmon device (ARPHRD_NETLINK) driver that can tap on netlink traffic, e.g.: Setup: modprobe nlmon ip link add type nlmon ip link set nlmon0 up Capture: netsniff-ng -i nlmon0 ... (or -i any) Teardown: ip link set nlmon0 down ip link del dev nlmon0 rmmod nlmon Provide information about the packet direction (user space or kernel space), so that dissector will show that properly.
