# device that connects the DUT to the test infrastructure.
# It has restrictive routes and is outside of flimflam's
# control. This makes the tests resilient to flimflam
# restarts and helps to ensure that the test is actually
# sending traffic on the cellular link
# * an OtherDeviceShutdownContext, which shuts down other
# network devices on the host. Again, this is to ensure
# that test traffic goes over the modem
# * A cellular test environment context, which lets us
# interact with the cell network.
