The type for ethernet interface errors.
val write : t -> ?src:Macaddr.t -> Macaddr.t -> Mirage_protocols.Ethernet.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 gets a buffer of
size (defaults to mtu) to fill with their payload. If
mtu, an error is returned.
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.
