No activity since 2018, uses python 2, wants switch(4) (removed in 2021)
and "Open vSwitch" programs we don't have.

I ran `nm' for an example as per README.md, but it did seemingly nothing
except destroying (on ^C) my pair(4) interfaces used with gelatod(8).

To be fair, that file says it is a heavy WIP fork for Free/OpenBSD that
might touch unrelated stuff, but perhaps this whole project halted and
its time to drop the experimental port?

FreeBSD does not have it, either.
