.dev_start()/.dev_stop() roughly corresponds to the local device's port
being ready. This is different from the remote client being connected
which is roughly link up or down. Emulate the device start/stop behavior
by separately tracking the start/stop state to determine if we should
allow packets to be queued to/from the remote client.
