func RestoreHostIPs(ipv6 bool, fromK8s, fromFS net.IP, cidr *cidr.CIDR) net.IP

RestoreHostIPs restores the router IPs (`cilium_host`) from a previous Cilium run. Router IPs from the filesystem are preferred over the IPs found in the Kubernetes resource (Node or CiliumNode), because we consider the filesystem to be the most up-to-date source of truth. The chosen router IP is then checked whether it is contained inside node CIDR (pod CIDR) range. If not, then the router IP is discarded and not restored.

The restored IP is returned.
