From 509f04959ad891d7f981f035ed461d51bd1f74b0 Mon Sep 17 00:00:00 2001

Subject: [PATCH] The use of <net/ppp_defs.h> isn't guranteed to exist on Linux
 (e.g. uclibc, buildroot, others)
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

The one provided by glibc simply includes <linux/ppp_defs.h>. This include is still needed on SunOS
