[0/5] Forward Error Correction

Message

With Display Stream Compression, bit error
in pixel stream can turn into a significant
corruption on the screen. DP1.4 adds support for
Forward Eror correction which uses Reed-Solomon
codes with which the sink can detect small
numbers of bit errors in compressed stream.
