Typo: double 'R' in BUFFERRS :-)

'in one OUTPUT buffer' vs 'in one input buffer'. Perhaps rewriting it like this is better:
<row><entry spanname="descr">If enabled the decoder expects to receive a single slice per buffer, otherwise
the decoder expects a single frame in per buffer. Applicable to the decoder, all codecs.
BTW: 'all codecs'? Your decoder hardware can handle e.g. MPEG-2 sliced input?
I thought slices were specific to e.g. MPEG4/H264? Just checking...

If I understand this right enabling this will 'activate' the V4L2_CID_MPEG_MFC51_VIDEO_H264_ADAPTIVE_RC_* controls.
So this makes me wonder whether this control shouldn't perhaps be MFC51 specific
as well. Alternatively, we can say something like: 'How macroblock rate control is
implemented will differ per device, so devices that implement this will have their
own set of controls.'
