+ * This set of counters corresponds to number of symbol errors in each FEC
+ * codeword received on the port.
+ *
+ * The number of symbol errors that may be detected is dependent on the type
+ * of FEC in use. For instance, RS-528 FEC supports detection of up to 7
+ * symbol errors, while RS-544 FEC supports detection of up to 15 symbol
+ * errors. The maximum number of errors that can be detected by the port's
+ * current FEC mode may be retrieved via the

+ * codeword contains more than SAI_PORT_ATTR_MAX_FEC_SYMBOL_ERRORS_DETECTABLE,
+ * the errors are placed in the next higher counter (so for the examples
+ * above, SAI_PORT_STAT_IF_IN_FEC_CODEWORD_ERRORS_S8 would be used for
+ * greater than 7 symbol errors when RS-528 FEC is used, and
+ * SAI_PORT_STAT_IF_IN_FEC_CODEWORD_ERRORS_S16 for greater than 15 symbol
