Linux 7.1-rc1 defaults IPV6_SIT to built-in, which means a sit0 device
always exists.  (I think this is unintentional and have sent a patch
to change it back to a module by default[1].)  Depending on which
interface, sit0 or the eth0 connected to the router, comes up first,
networking may end up not working.  Make our interface handling more
robust by only bringing the interfaces from the router up, rather than
all interfaces unconditionally.

Not sure whether maybe it would be a good idea to check
type = 1 (ARPHRD_ETHER) as well?
