+/**
+ * struct ethtool_fec_stats - statistics for IEEE 802.3 FEC
+ * @corrected_blocks: number of received blocks corrected by FEC
+ * Reported to user space as %ETHTOOL_A_FEC_STAT_CORRECTED.
+ *
+ * Equivalent to `30.5.1.1.17 aFECCorrectedBlocks` from the standard.
+ *
+ * @uncorrectable_blocks: number of received blocks FEC was not able to correct
+ * Reported to user space as %ETHTOOL_A_FEC_STAT_UNCORR.
+ *
+ * Equivalent to `30.5.1.1.18 aFECUncorrectableBlocks` from the standard.
+ *
+ * @corrected_bits: number of bits corrected by FEC
+ * Similar to @corrected_blocks but counts individual bit changes,
+ * not entire FEC data blocks. This is a non-standard statistic.
+ * Reported to user space as %ETHTOOL_A_FEC_STAT_CORR_BITS.
+ *
+ * @lane: per-lane/PCS-instance counts as defined by the standard
+ * @total: error counts for the entire port, for drivers incapable of reporting
+ * per-lane stats
+ *
+ * Drivers should fill in either only total or per-lane statistics, core
+ * will take care of adding lane values up to produce the total.
