Expand description

An execution context for ARP providing functionality from the IP layer.

Required Methods§

Source

fn on_arp_packet( &mut self, bindings_ctx: &mut BC, device: &Self::DeviceId, frame_src: D::Address, sender_hwaddr: D::Address, sender_addr: Ipv4Addr, target_addr: Ipv4Addr, is_arp_probe: bool, ) -> bool

Dispatches a received ARP Request or Reply to the IP layer.

The IP layer may use this packet to update internal state, such as facilitating Address Conflict Detection (RFC 5227).

frame_src is the link address in the L2 Frame that carried this ARP packet, while sender_hwaddr is the sender_hardware_addr field from the ARP header.

Returns whether the target_addr is assigned on the device. This is used by ARP to send responses to the packet (if applicable).
