func Extend(dev packet.NetworkDevice, config *Config) packet.NetworkDevice

Extend creates a geographic link between the given device and the returned device.

Internally, this creates the following link:

external <=> dev

where:

- dev is the device passed as argument

- external is the device returned to the caller

Packets flowing through this chain experience the configured delay in both directions.

We create two goroutines for forwarding packets, which are closed when dev is closed.

type Config struct {
	// Delay is the propagation delay.
	Delay time.Duration

	// Log enables logging of delivered packets.
	Log bool
}

Config configures a geographic point-to-point link.
