From 566cac17c3b5cfd85eb5bb1764c6cd29347b390d Mon Sep 17 00:00:00 2001 From: Sascha Hauer Date: Thu, 2 Jul 2015 08:36:08 +0200 Subject: net: Move library functions to net/lib.c Some network related functions are also needed when networking is disabled. Move these to a separate file which is always compiled.
