In this sub-mode, the RS-FEC engine detects and corrects errors.

If a codeword with up to 7 symbol errors is received, the errors are corrected and the data is passed to the Integrated 100G Ethernet.

If a codeword with 8 or more symbol errors is received, the erroneous data is passed to the Integrated 100G Ethernet with some of the 2-bit synchronization headers corrupted within the 66b/64b encoded stream. This causes the Integrated 100G Ethernet to discard any data packets that are wholly or partially contained within the affected codeword.
