Types

type Endpoint

type Endpoint struct {
	nested.Endpoint
}

Endpoint is an ethernet endpoint.

It adds an ethernet header to packets before sending them out through its inner link endpoint and consumes an ethernet header before sending the packet to the stack.

func New

func New(ep stack.LinkEndpoint) *Endpoint

New returns an ethernet link endpoint that wraps an inner link endpoint.

func (*Endpoint) ARPHardwareType

func (e *Endpoint) ARPHardwareType() header.ARPHardwareType

ARPHardwareType implements stack.LinkEndpoint.

func (*Endpoint) AddHeader

func (*Endpoint) AddHeader(local, remote tcpip.LinkAddress, proto tcpip.NetworkProtocolNumber, pkt *stack.PacketBuffer)

AddHeader implements stack.LinkEndpoint.

func (*Endpoint) Capabilities

func (e *Endpoint) Capabilities() stack.LinkEndpointCapabilities

Capabilities implements stack.LinkEndpoint.

func (*Endpoint) DeliverNetworkPacket

func (e *Endpoint) DeliverNetworkPacket(_, _ tcpip.LinkAddress, _ tcpip.NetworkProtocolNumber, pkt *stack.PacketBuffer)

DeliverNetworkPacket implements stack.NetworkDispatcher.

func (*Endpoint) LinkAddress

func (e *Endpoint) LinkAddress() tcpip.LinkAddress

LinkAddress implements stack.LinkEndpoint.

func (*Endpoint) MTU

func (e *Endpoint) MTU() uint32

MTU implements stack.LinkEndpoint.

func (*Endpoint) MaxHeaderLength

func (e *Endpoint) MaxHeaderLength() uint16

MaxHeaderLength implements stack.LinkEndpoint.

func (*Endpoint) WritePackets

func (e *Endpoint) WritePackets(r stack.RouteInfo, pkts stack.PacketBufferList, proto tcpip.NetworkProtocolNumber) (int, tcpip.Error)

WritePackets implements stack.LinkEndpoint.

func (*Endpoint) WriteRawPacket

func (e *Endpoint) WriteRawPacket(pkt *stack.PacketBuffer) tcpip.Error

WriteRawPacket implements stack.LinkEndpoint.
