[OpenWrt-Devel] [PATCH] gre: Generic Routing Encapsulation package support

[Hans Dedecker]

Main use case behind the network option is being able to add the
ethernet gre interface to a bridge interface as a hotplug interface
when the gre ethernet interface becomes active (as you cannot
configure the gre(v6)tap interface in the uci bridge ifname option);
therefore only the gretap and grev6tap interfaces support this option.
The network option has no link to the assignment of a static IP
address on a gre interface; I would expect it to work as described
below independent from the network option.
If the network option is not the most optimal/elegant solution for the
use case described above I'm all ears for other suggestions/solutions.

Bye,
Hans
