Because ens19 seems no network, if use ens19 then ipv6 will not work.
The config in the past sometimes ipv6 not work I think is due to somehow
SIT 6in4 tunnel sometimes use ens19 instead of ens18.

Sometimes, there's a new route appear in my `ip -6 r`:
default nhid 715021918 via fe80::284:e5ff:fe28:829d dev eth0 proto ra metric 1024 expires 24sec pref medium
There's also these lines appear in my `ip -a`:
inet6 2606:a8c0:3:8cd:246:d3ff:fed8:155d/64 scope global dynamic mngtmpaddr noprefixroute
valid_lft 86398sec preferred_lft 14398sec
It seems sometimes Crunchbits maybe send some ipv6 RA (router
advertisement) message to my VPS and cause my VPS to add these lines.
This will break ipv6 of my VPS. I searched online, it seems I can use
`IPv6AcceptRA=false` in my systemd network config file, and it fixed the
issue. Not sure if this is the correct way. I also don't quite
understand RA.
Maybe another way to fix the issue is to accept RA and let is to
configure my ipv6 correctly somehow. But this RA message only appears
sometimes and not always. So I think just disable it maybe is a better
way.
