Provides control over a pair of network devices.

A DevicePair is a simpler version of Device that “shorts” two network device interfaces, named its “left” and “right” ends. The internal state of a DevicePair is not accessible, like it is for Device and it provides a more streamlined (and considerably faster) pair of [fuchsia.hardware.network/Device]s. The transmit side of each port of the left end is connected to the receive side of the port with the same identifier on the right end, and vice-versa. A DevicePair’s port online signal is handled internally (online if any of the ends has an active data session). If MAC addresses are provided on creation, the only supported MAC filtering mode is PROMISCUOUS.

This protocol encodes the underlying object’s lifetime in both directions; the underlying object is alive iff both ends of the protocol are open. That is:

• Closing the client end causes the object to be destroyed.
• Observing a closure of the server end indicates the object no longer exists.

Variants

AddPort

Adds a logical port to this device pair.

• request config port configuration.

• error ZX_ERR_INVALID_ARGS if config is invalid.
• error ZX_ERR_ALREADY_EXISTS if the provided port identifier is already in use.

Fields

config: DevicePairPortConfig

responder: DevicePairAddPortResponder

RemovePort

Removes a logical port created by [fuchsia.net.tun/DevicePair.AddPort].

• request id identifier of the port to remove.

• error ZX_ERR_NOT_FOUND if id does not map to an existing port.

Fields

id: u8

responder: DevicePairRemovePortResponder

GetLeft

Connects to the underlying left device endpoint.

• request device handle serve the left device endpoint on.

Fields

device: ServerEnd<DeviceMarker>

control_handle: DevicePairControlHandle

GetRight

Connects to the underlying right device endpoint.

• request device handle serve the right device endpoint on.

Fields

device: ServerEnd<DeviceMarker>

control_handle: DevicePairControlHandle

GetLeftPort

Connects to an underlying left port.

• request id requested port identifier.
• request port grants access to the requested port on the left device.

Fields

id: u8

port: ServerEnd<PortMarker>

control_handle: DevicePairControlHandle

GetRightPort

Connects to an underlying right port.

• request id requested port identifier.
• request port grants access to the requested port on the right device.

Fields

id: u8

port: ServerEnd<PortMarker>

control_handle: DevicePairControlHandle
