Address resolution protocol, translating network addresses (e.g. IPv4) into link layer addresses (MAC).
val disconnect : t -> unit Lwt.tDisconnect from the ARP layer. While this might take some time to complete, it can never result in an error.
val pp_error : error Fmt.tpp_error is the pretty-printer for errors.
val pp : t Fmt.tPrettyprint cache contents
val get_ips : t -> Ipaddr.V4.t listget_ips arp gets the bound IP address list in the arp value.
val set_ips : t -> Ipaddr.V4.t list -> unit Lwt.tset_ips arp sets the bound IP address list, which will transmit a GARP packet also.
val remove_ip : t -> Ipaddr.V4.t -> unit Lwt.tremove_ip arp ip removes ip to the bound IP address list in the arp value, which will transmit a GARP packet for any remaining IPs in the bound IP address list after the removal.
val add_ip : t -> Ipaddr.V4.t -> unit Lwt.tadd_ip arp ip adds ip to the bound IP address list in the arp value, which will transmit a GARP packet also.
val query : t -> Ipaddr.V4.t -> (Macaddr.t, error) Stdlib.result Lwt.tquery arp ip queries the cache in arp for an ARP entry corresponding to ip, which may result in the sender sleeping waiting for a response.
val input : t -> Cstruct.t -> unit Lwt.tinput arp frame will handle an ARP frame. If it is a response, it will update its cache, otherwise will try to satisfy the request.
