From 42fc558ee36561c3a024d21e89aacf68b88d25a0 Mon Sep 17 00:00:00 2001 From: Donald Sharp Date: Mon, 29 Jul 2019 14:53:58 -0400 Subject: [PATCH] zebra, tests: Remove ROUTE_ENTRY_NEXTHOPS_CHANGED The flag ROUTE_ENTRY_NEXTHOPS_CHANGED is only ever set or unset. Since this flag is not used for anything useful, remove from system. By changing this flag we have re-ordered `internalStatus' of json output of zebra rib routes. Go through and fix up tetsts to use the new values.
