From d9cf0a76db5e428692f2489901c9787b1fd30eee Mon Sep 17 00:00:00 2001 From: Thomas Petazzoni Date: Fri, 3 Apr 2015 14:01:59 +0200 Subject: [PATCH] softether: add patch to fix build on uClibc toolchain without ifaddr support This commit adds a patch to softether to make sure it doesn't use the ifaddrs functions when they are not provided by the C library, which can be the case with certain external uClibc toolchains.
