ssh stalls on IPv6
Using a link-local connection from NetworkManager over USB:
ssh purism@fe80::18be:46be:45d6:951c%enp0s20u1i2It works for a while, at least 15 seconds, and then it waits (for a lack of activity?) to stall. I'm not sure if anything else but SSH is affected, and not sure yet what's happening on the TCP level. New connections can be established no problem.
