[OpenWrt-Devel] [PATCH] libnl: split into smaller libraries

[Alexandru Ardelean]

From: Alexandru Ardelean <aa at ocedo.com>

The idea is that we may only need the libnl core, 
or libnl-route or libnl-nf libs, but maybe not all of them.

This way we can select which ones we need without bloating the
firmware image too much.
