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

config NETDEV_LATEINIT
	bool "Late driver initialization"
	default n
	---help---
		Normally, networking initialization occur in the later phase of the
		boot process in the function up_initialize() when it calls the
		driver initialization function, up_netintialize().  This
		initialization occurs after a sufficient about of the OS has been
		initialized so that driver registration can be performed, but
		before the completion of OS initialization and before the first
		application is started.

		In a few situations, however, you may want to suppress this early
		network driver initialization.  As examples:

			- If you are using SLIP or PPPD, then there will be no network
			  driver to be initialized,
			- Certain multi-network configurations where a simple call to
			  up_netinitialize() may be insufficient, and
			- Situations where there are other board-level hardware
			  dependencies so that the hardware is not in an appropriate
			  state for up_netinitialize() to be called.

		Examples of this latter situation includes such things as network
		drivers that required some setup via an I2C I/O expander, or network
		drivers that depend on USB, SPI, I2C, PCI, serial, or other
		interfaces that may not be ready when up_netiniailize() is normally
		called.

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.

config NET_SLIP_MTU

	---help---
		Provides the size of the SLIP packet buffers.

		The Linux slip module hard-codes its MTU size to 296 (40 bytes for
		the IP+TPC headers plus 256 bytes of data).  So you might as well
		set CONFIG_NET_SLIP_MTU to 296 as well.

		There may be an issue with this setting, however.  I see that Linux
		uses a MTU of 296 and window of 256, but actually only sends 168
		bytes of data: 40 + 128.  I believe that is to allow for the 2x
		worst cast packet expansion.  Ideally we would like to advertise the
		256 MSS, but restrict transfers to 128 bytes (possibly by modifying
		the tcp_mss() macro).
