+FEC
+---
+
+Supports Forward error correction. Forward error correction (FEC) is 
a bit error correction mode.
+It adds error correction information to data packets at the transmit 
end, and uses the error correction
+information to correct the bit errors generated during data packet 
transmission at the receive end. This
+improves signal quality but also brings a delay to signals. This 
function can be enabled or disabled as required.

+* **[implements] eth_dev_ops**: ``fec_get_capability``, ``fec_get``, 
``fec_set``.
+* **[provides]   rte_eth_fec_capa**: ``speed:ETH_SPEED_NUM_*``, 
``capa:RTE_ETH_FEC_MODE_TO_CAPA()``.
+* **[related]    API**: ``rte_eth_fec_get_capability()``, 
``rte_eth_fec_get()``, ``rte_eth_fec_set()``.

Feature doc looks good, thanks for adding this.

Can you add another patch in this series to update .ini files for hns3 & 
cxgbe to advertise FEC feature?

ok. I will do it in next version.

I suppose updating drivers can be done in the same patch.
