From 6034b5c703cdb6f55d2847661fd1415184942ee2 Mon Sep 17 00:00:00 2001 From: Koen Aerts Date: Tue, 13 Aug 2019 15:02:19 +0200 Subject: [PATCH] router: close socket upon NETEV_IFINDEX_CHANGE Make sure the socket is closed in a case where the bridge goes down as a result of NO-CARRIER on the bridge. If not present Router Discovery and Router Advertisement will break permanently after the bridge went down.
