Class type
The type for ethernet interface errors.
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 ->

?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 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.
