ndp-proxy-go: Proxy ISP provided /64 Prefix from WAN to LAN

[Monviech (Cedrik)]

Experimental PPPoE support is in 25.7.9.

The last feature I added is PF table (firewall alias) support to help with the network segmentation for highly dynamic setups.

It will most likely hit 25.7.10.

With that the proxy should be complete for now, I personally do not miss any feature when using it, it just worksTM and is quite possibly the leading most complete implementation to fix IPv6 for many setups.

I would call it generic since you can chain the proxy over multiple routers. You dont even need DHCPv6-PD anymore, this proxy handles dynamic IPv6 so gracefully that you won't believe it.
