		units used for reception.  This is also equal to the number of RX
		descriptors that will be allocated  The selected value must be an
		even power of 2.

config SAMD5E5_GMAC_NTXBUFFERS
	int "Number of TX buffers"
	default 8
	---help---
		GMAC buffer memory is segmented into full Ethernet packets (size
		NET_BUFSIZE bytes).  This setting provides the number of such packets
		that can be in flight.  This is also equal to the number of TX
		descriptors that will be allocated.

config SAMD5E5_GMAC_PREALLOCATE
	bool "Preallocate buffers"
	default n
	---help---
		Buffer an descriptor many may either be allocated from the memory
		pool or pre-allocated to lie in .bss.  This options selected pre-
		allocated buffer memory.

config SAMD5E5_GMAC_NBC
	bool "Disable Broadcast"
	default n
	---help---
		Select to disable receipt of broadcast packets.

config SAMD5E5_GMAC_PHYADDR
	int "PHY address"
	default 1
	---help---
		The 5-bit address of the PHY on the board.  Default: 1

config SAMD5E5_GMAC_PHYINIT
	bool "Board-specific PHY Initialization"
	default n
	---help---
		Some boards require specialized initialization of the PHY before it can be used.
		This may include such things as configuring GPIOs, resetting the PHY, etc.  If
		SAMD5E5_GMAC_PHYINIT is defined in the configuration then the board specific logic must
		provide sam_phyinitialize();  The SAMD5E5 GMAC driver will call this function
		one time before it first uses the PHY.

config SAMD5E5_GMAC_AUTONEG
	bool "Use autonegotiation"
	default y
	---help---
		Use PHY autonegotiation to determine speed and mode

	bool "10 Mbps"
	---help---
		If SAMD5E5_GMAC_AUTONEG is not defined, then this may be defined to select 10 MBps

	bool "100 Mbps"
