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.

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.

help
Enables Ethernet bridging where packets can be transparently
forwarded across interfaces registered to a bridge.

select SHELL
help
Enables shell utility to manage bridge configuration interactively.
config NET_ETHERNET_BRIDGE_DEFAULT
bool "Declare one bridge instance for shell usage"
depends on NET_ETHERNET_BRIDGE_SHELL
default y
help
If the bridge shell is the sole user of the bridge code then
it needs at least one bridge instance to be useful.
Say y if this is the case. If you only want to inspect
existing bridge instances then say n.
