		Network interface driver and PHY selections.  This options enables
		selection of drivers for external Ethernet MAC chips.  The majority
		of MCUs, however, have built-in, internal Ethernet MAC peripherals
		and that Ethernet support is selected in the MCU-specific
		configuration menus.

		Most Ethernet MAC drivers, whether internal or external, will
		require configuration of an external PHY device.  That external PHY
		device is also selected via this menu.
