+  =====================================  ======  ==========================
+
+``ETHTOOL_A_FEC_ACTIVE`` is the bit index of the FEC link mode currently
+active on the interface. This attribute may not be present if device does
+not support FEC.
+
+``ETHTOOL_A_FEC_MODES`` and ``ETHTOOL_A_FEC_AUTO`` are only meaningful when
+autonegotiation is disabled. If ``ETHTOOL_A_FEC_AUTO`` is non-zero driver will
+select the FEC mode automatically based on the parameters of the SFP module.
+This is equivalent to the ``ETHTOOL_FEC_AUTO`` bit of the ioctl interface.
+``ETHTOOL_A_FEC_MODES`` carry the current FEC configuration using link mode
+bits (rather than old ``ETHTOOL_FEC_*`` bits).

+  ``ETHTOOL_A_FEC_AUTO``                 bool    FEC mode auto selection
+  =====================================  ======  ==========================
+
+``FEC_SET`` is only meaningful when autonegotiation is disabled. Otherwise
+FEC mode is selected as part of autonegotiation.
+
+``ETHTOOL_A_FEC_MODES`` selects which FEC mode should be used. It's recommended
+to set only one bit, if multiple bits are set driver may choose between them
+in an implementation specific way.
+
+``ETHTOOL_A_FEC_AUTO`` requests the driver to choose FEC mode based on SFP
+module parameters. This does not mean autonegotiation.
