Re: [PATCH net-next 08/11] net: dsa: mv88e6xxx: add port duplex setter

 	int (*port_set_link)(struct mv88e6xxx_chip *chip, int port, int link);

+	/* Port's MAC duplex mode
+	 *
+	 * Use DUPLEX_HALF or DUPLEX_FULL to force half or full duplex, or
+	 * DUPLEX_UNKNOWN for normal duplex detection.

Hi Vivien

Again, i think DUPLEX_UNFORCED, or DUPLEX_AUTO would be better.
