+ * struct i40e_stats - definition for an ethtool statistic
+ * @stat_string: statistic name to display in ethtool -S output
+ * @sizeof_stat: the sizeof() the stat, must be no greater than sizeof(u64)
+ * @stat_offset: offsetof() the stat from a base pointer
+ *
+ * This structure defines a statistic to be added to the ethtool stats buffer.
+ * It defines a statistic as offset from a common base pointer. Stats should
+ * be defined in constant arrays using the I40E_STAT macro, with every element
+ * of the array using the same _type for calculating the sizeof_stat and
+ * stat_offset.
+ *
+ * The @sizeof_stat is expected to be sizeof(u8), sizeof(u16), sizeof(u32) or
+ * sizeof(u64). Other sizes are not expected and will produce a WARN_ONCE from
+ * the i40e_add_ethtool_stat() helper function.
+ *
+ * The @stat_string is interpreted as a format string, allowing formatted
+ * values to be inserted while looping over multiple structures for a given
+ * statistics array. Thus, every statistic string in an array should have the
+ * same type and number of format specifiers, to be formatted by variadic
+ * arguments to the i40e_add_stat_string() helper function.
