Parameter `MakeV4V6.Ethernet`

type nonrec error = private [>

| `Exceeds_mtu

]

The type for ethernet interface errors.

val pp_error : error Fmt.t

pp_error is the pretty-printer for errors.

type t

The type representing the internal state of the ethernet layer.

val disconnect : t -> unit Lwt.t

Disconnect from the ethernet layer. While this might take some time to complete, it can never result in an error.

val write : 
  t ->
  ?src:Macaddr.t ->
  Macaddr.t ->
  Ethernet.Packet.proto ->
  ?size:int ->
  (Cstruct.t -> int) ->
  (unit, error) result Lwt.t

write eth ~src dst proto ~size payload outputs an ethernet frame which header is filled by eth, and its payload is the buffer from the call to payload. Payload gets a buffer of size (defaults to mtu) to fill with their payload. If size exceeds mtu, an error is returned.

val mac : t -> Macaddr.t

mac eth is the MAC address of eth.

val mtu : t -> int

mtu eth is the Maximum Transmission Unit of the eth i.e. the maximum size of the payload, excluding the ethernet frame header.

val input : 
  arpv4:(Cstruct.t -> unit Lwt.t) ->
  ipv4:(Cstruct.t -> unit Lwt.t) ->
  ipv6:(Cstruct.t -> unit Lwt.t) ->
  t ->
  Cstruct.t ->
  unit Lwt.t

input ~arpv4 ~ipv4 ~ipv6 eth buffer decodes the buffer and demultiplexes it depending on the protocol to the callback.
