// IMPORTANT!!! if you make a change to the tests here you should
// check whether the same change should be made to the tests under
// the PPP interface.

// NOTE: these test are only as reliable as UDP across the internet
// over a radio link.  The tests expect an NTP server to respond
// to UDP packets and, if configured, an echo server to respond
// to UDP packets.  This simply may not happen.  Please be patient.
