From 58312125da5806308bd69e075fedae30f8cf7794 Mon Sep 17 00:00:00 2001 From: Ido Schimmel Date: Fri, 23 Dec 2016 09:32:50 +0100 Subject: [PATCH] mlxsw: spectrum_router: Correctly remove nexthop groups At the end of the nexthop initialization process we determine whether the nexthop should be offloaded or not based on the NUD state of the neighbour representing it. After all the nexthops were initialized we refresh the nexthop group and potentially offload it to the device, in case some of the nexthops were resolved. Make the destruction of a nexthop group symmetric with its creation by marking all nexthops as invalid and then refresh the nexthop group to make sure it was removed from the device's tables.
