menuconfig NET_L2_ETHERNET
	bool "Enable Ethernet support"
	help
	  Add support for Ethernet, enabling selecting relevant hardware drivers.
	  If NET_SLIP_TAP is selected, NET_L2_ETHERNET will enable to fully
	  simulate Ethernet through SLIP.

if NET_L2_ETHERNET

module = NET_L2_ETHERNET
module-dep = NET_LOG
module-str = Log level for Ethernet L2 layer
module-help = Enables Ethernet L2 to output debug messages.

config NET_L2_ETHERNET_MGMT
	bool "Enable Ethernet network management interface"
	select NET_MGMT
	select NET_MGMT_EVENT
	help
	  Enable support net_mgmt Ethernet interface which can be used to
	  configure at run-time Ethernet drivers and L2 settings.

config NET_VLAN
	bool "Enable virtual lan support"
	help
	  Enables virtual lan (VLAN) support for Ethernet.

config NET_VLAN_COUNT
	int "Max VLAN tags supported in the system"
	default 1
	range 1 255
	depends on NET_VLAN
	help
	  How many VLAN tags can be configured.

config NET_ARP
	bool "Enable ARP"
	default y
	depends on NET_IPV4
	help
	  Enable ARP support. This is necessary on hardware that requires it to
	  get IPv4 working (like Ethernet devices).

config NET_ARP_TABLE_SIZE
	int "Number of entries in ARP table."
	depends on NET_ARP
	default 2
	help
	  Each entry in the ARP table consumes 22 bytes of memory.

config NET_ARP_GRATUITOUS
	bool "Support gratuitous ARP requests/replies."
	depends on NET_ARP
	default y
	help
	  Gratuitous in this case means a ARP request or reply that is not
	  normally needed according to the ARP specification but could be used
	  in some cases. A gratuitous ARP request is a ARP request packet where
	  the source and destination IP are both set to the IP of the machine
	  issuing the packet and the destination MAC is the broadcast address
	  ff:ff:ff:ff:ff:ff. Ordinarily, no reply packet will occur.
	  A gratuitous ARP reply is a reply to which no request has been made.

if NET_ARP
module = NET_ARP
module-dep = NET_LOG
module-str = Log level for IPv4 ARP
module-help = Enables core ARP code to output debug messages.
