Fix this by marking it as progressive in the capture setup, which will then select the correct interrupt mode. Tested on both Gen2 and Gen3 with the result of a doubling of the frame rate for V4L2_FIELD_ALTERNATE. From a PAL video source the frame rate is now 50, which is expected for alternate field capture.
