Hi, thank you for this.

https://klarasystems.com/articles/using-the-freebsd-rack-tcp-stack/ mentions
this needs to be set in /etc/src.conf :

WITH_EXTRA_TCP_STACKS=1

Is this still the case? Context here is -current both in a vm and bare
metal, on various machines, on various connections, from DSL to 10Gb.

Is there a method (yet) for enabling this functionality in various -RELENG
maybe where one can compile in a vm built for that purpose, then
transferring to the production vm?

Would it be expected to work on arm64?

What testing would you like doing?
