No, it doesn't. It has the 'input' field which identifies it.
A V4L2 capture device can have any number of inputs (enumerable by the
app). Any of those inputs can be tuners-- struct v4l2_input.type ==
V4L2_INPUT_TYPE_TUNER. If input N is a tuner, then access it with
v4l2_tuner.input = N and v4l2_frequency.input = N.
struct v4l2_frequency.port should have been struct v4l2_frequency.input,
and add FREQ2:
