Control forwarding per NetworkEndpoint
...instead of per NetworkProtocol to better conform with linux
(https://www.kernel.org/doc/Documentation/networking/ip-sysctl.txt):
```
conf/interface/*
forwarding - BOOLEAN
Enable IP forwarding on this interface. This controls whether packets
received _on_ this interface can be forwarded.
```
Fixes #5932.
