+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.
