An Adaptive Sync SDP allows a DP p[rotocol converter to forward Adaptive
Sync video, with minimul buffering overhead within the protocol
converter. An Adaptive-Sync-capable DP protocol converter shall indicate
Adaptive-Sync SDP support by setting the related bit to DPCD register
in addition to setting the MSA Ignore bit.
