18 Specifies the MAC address that was assigned to the network device.

26 Specifies the MAC address that was last used by the boot
27 program; should be used in cases where the MAC address assigned
28 to the device by the boot program is different from the
29 local-mac-address property.

117 The size of the controller\'s receive fifo in bytes. This is used
118 for components that can have configurable receive fifo sizes,
119 and is useful for determining certain configuration settings
120 such as flow control thresholds.

125 Specifies a reference to a node representing a SFP cage.
128 $ref: /schemas/types.yaml#definitions/uint32
130 The size of the controller\'s transmit fifo in bytes. This
131 is used for components that can have configurable fifo sizes.
135 Specifies the PHY management type. If auto is set and fixed-link
136 is not specified, it uses MDIO for management.
