Parameters

module Ethernet : Mirage_protocols_lwt.ETHERNET

module Time : Mirage_time_lwt.S

Signature

include Mirage_protocols_lwt.ARP

include Mirage_device.S with type 'a io = 'a Lwt.t

type 'a io = 'a Lwt.t

The type for potentially blocking I/O operation

type t

The type representing the internal state of the device

val disconnect : t -> unit io

Disconnect from the device. While this might take some time to complete, it can never result in an error.

type ipaddr = Ipaddr.V4.t

type buffer = Cstruct.t

type macaddr = Macaddr.t

type repr

type error = private [>

| Mirage_protocols.Arp.error

]

The type for ARP errors.

val pp_error : error Fmt.t

pp_error is the pretty-printer for errors.

val to_repr : t -> repr io

Prettyprint cache contents

val pp : repr Fmt.t

val get_ips : t -> ipaddr list

get_ips arp gets the bound IP address list in the arp value.

val set_ips : t -> ipaddr list -> unit io

set_ips arp sets the bound IP address list, which will transmit a GARP packet also.

val remove_ip : t -> ipaddr -> unit io

remove_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 -> unit io

add_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 -> (macaddr, error) result io

query 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 -> buffer -> unit io

input arp frame will handle an ARP frame. If it is a response, it will update its cache, otherwise will try to satisfy the request.

val connect : Ethernet.t -> t Lwt.t
