Qing Li c7ab66020f The proxy arp entries could not be added into the system over the ... IFF_POINTOPOINT link types. The reason was due to the routing entry returned from the kernel covering the remote end is of an interface type that does not support ARP. This patch fixes this problem by providing a hint to the kernel routing code, which indicates the prefix route instead of the PPP host route should be returned to the caller. Since a host route to the local end point is also added into the routing table, and there could be multiple such instantiations due to multiple PPP links can be created with the same local end IP address, this patch also fixes the loopback route installation failure problem observed prior to this patch. The reference count of loopback route to local end would be either incremented or decremented. The first instantiation would create the entry and the last removal would delete the route entry.
