From c8ac572154981ca833dad92d7ee7aa62b88087cc Mon Sep 17 00:00:00 2001 From: Hans Dedecker Date: Sat, 21 Jan 2017 15:40:13 +0100 Subject: [PATCH 1/1] ndp: don't scan netlink attributes in case of netlink route event In case a netlink route event is received for a default route netlink data attributes were faulty processed as neigbor netlink data. Fix this by not processing any netlink attribute for any route event.
