urndis and tethering on a Google Pixel 6 phone (or not)

[David Brownlee <abs%absd.org@localhost>]

Has anyone been able to tether using urndis on a Google Pixel 6?

It's not picked up automatically, and just as a test I added it(*) to
urndis_devs in sys/dev/usb/if_urndis.c, but it doesn't complete
autoconfig - I suspect it might need to be poked in some special way
to actually be an urndis, or else is now a new-new-linux-urndis2 thing

(*) The phone attaches as multiple devices based on whether it's
trying to offer USB tether, combined with whether USB debug is
enabled.
