+ The Motorcomm YT921x series is a family of Ethernet switches with up to 8
+ internal GbE PHYs and up to 2 GMACs, including:

+ - YT9213NB: 2 GbE PHYs (Port 1/3) + 1 GMAC (Port 9)
+ - YT9214NB: 2 GbE PHYs (Port 1/3) + 2 GMACs (Port 8-9)
+ - YT9218N: 8 GbE PHYs (Port 0-7)
+ - YT9218MB: 8 GbE PHYs (Port 0-7) + 2 GMACs (Port 8-9)
+
+ Any port can be used as the CPU port.
