I have worked really hard to make sure ipv6 "just works" (still) in
the upcoming openwrt 22.03 release, treating it as *my* primary ip
stack, at least.

But I spent most of my time fixing a string of fq-codel & ATF wifi
regressions on the mt76 chips and (especially) not on testing the
various encapsulations, and am out of time.

If y'all care about ipv6, please lean in, test, and file bugs on these
last release candidates before it goes final?

The network you save may be your own.
