Description of problem:
Some old networking defvices send (a somewhat bogus) NTPv1 requests when they are compatible with NTPv3 or even NTPv4.

How reproducible:

Expected results:
It is welcome to reply to such requests like the reference implementation, it is harmless. Optionally add a switch/config option to enable replies to such devices.
