200GBASE-R and 400GBASE-R MAC and PCS with 256b/257b transcoding, RS(544,514) KP4 FEC and 8x50G or 4x100G PMA lanes.
Planned. This block is specified in the catalog with its interfaces and targets. No implementation exists yet; the skeleton command below generates a lint-clean shell with its ports and registers.
