config NETDEV_MULTINIC
	bool "Multiple NIC support"
	default n
	---help---
		Select this option if you board and/or MCU are capable of supporting
		multiple Ethernet MAC drivers.

config NET_DUMPPACKET
	bool "Enable packet dumping"
	depends on DEBUG
	default n
	---help---
		Some Ethernet MAC drivers supporting dumping of received and
		transmitted packets as a debug option.  This setting enables that
		debug option. Also needs DEBUG.

		are not selected.  This allows for focused, unit-level debug of
		the NSH network initialization logic.
