5.1.13. Reed-Solomon (RS) Forward Error Correction (FEC) Generation and Insertion
The IP demultiplexes the data on the link into four RS blocks to create the RS parity words. The parity data are interleaved onto the data lanes.
The primitive polynomial used to form the GF (256) field is:
p(x)= X8 + x4 + x3 + x2 + 1
The corresponding RS code generator polynomial used by the encoder is:
g(x) = x4 + 15x3 + 54x2 + 120x + 64
