menuconfig NET_L2_ETHERNET
bool "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.

module = NET_L2_ETHERNET
module-dep = NET_LOG
module-str = Log level for Ethernet L2 layer

config NET_L2_ETHERNET_MGMT
bool "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 "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 "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

config NET_ETHERNET_BRIDGE
bool "Ethernet Bridging support"
select NET_PROMISCUOUS_MODE
help
Enables Ethernet bridging where packets can be transparently
forwarded across interfaces registered to a bridge.

bool "Ethernet Bridging management shell"

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.
config NET_ETHERNET_FORWARD_UNRECOGNISED_ETHERTYPE
bool "Forward unrecognized EtherType frames further into net stack"
default y if NET_SOCKETS_PACKET
help
When enabled, the Ethernet L2 will forward even those frames for which
it does not recognize the EtherType in the header. By default, such
frames are dropped at the L2 processing.
