include Mirage_protocols.ICMP with type ipaddr = Ipaddr.V4.t
type t
val disconnect : t -> unit Lwt.t
type ipaddr = Ipaddr.V4.t
type error
val pp_error : error Fmt.t
val input : t -> src:ipaddr -> dst:ipaddr -> Cstruct.t -> unit Lwt.t
val write : t -> ?src:ipaddr -> dst:ipaddr -> ?ttl:int -> Cstruct.t -> (unit, error) Stdlib.result Lwt.t
val connect : unit -> t Lwt.t
val listen : t -> ipaddr -> (Cstruct.t -> unit Lwt.t) -> unit Lwt.t

listen t addr fn attempts to create an unprivileged listener on IP address addr.

When a packet is received, the callback fn will be called in a fresh background thread. The callback will be provided a buffer containing an IP datagram with an ICMP payload inside.

The thread returned by listen blocks until the stack is disconnected.
