DEV_ADDR is defined but not used. Use it in address setting.
Do the same with IPv6 for consistency.

As all the testing addresses are in the same subnet and egress device ==
ingress device. We need enable forwarding to get the route entry.

Also disable rp_filer separately as some distributions enable it in
startup scripts.

The IPv4 testing address are all in 192.51.100.0 subnet. It doesn't make
sense to set a 198.51.100.1 local address. Should be a typo.

Remove the existing way to create netdevsim over rtnetlink and move the
netdev creation/destruction to dev probe, so for every probed port,
a netdevsim-netdev instance is created.

Adjust selftests to work with new interface.
