Thanks for making this machine available.

On Mac OS, there are, by default, bizarre restrictions on IP datagram 
in the protocol stack.

Would it be possible to put this configuration into effect:

    sysctl -w net.inet.udp.maxdgram=65535

or something similar, if that doesn't work on the M1?

(In a persistent way that surives reboots.)

I have a test case involving UDP that works on numerous platforms, the
oddball being MacOS, where I have to do the above.
