Interlaced video can have different scan order: Top Field First or Bottom Field First
In case of video with interlaced content, this information should be propagated from the userland to the DRM kernel driver that will process the deinterlacing starting with the top or the bottom field first. That's why we introduce this new flag definition DRM_MODE_FB_BFF (Bottom Field First) that should be used jointly with the already existing DRM_MODE_FB_INTERLACED flag incase of interlaced video with Bottom Field First scan order should be processed.
