Class type
The type for ethernet interface errors.
val pp_error : error Fmt.t
pp_error
is the pretty-printer for errors.
type macaddr = Macaddr.t
The type for unique MAC identifiers.
val write :
t ->
?src:macaddr ->
macaddr ->
Mirage_protocols.Ethernet.proto ->
?size:int ->
(buffer -> int) ->
(unit, error) Stdlib.result io
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.
