Date: Fri, 1 Sep 2017 10:58:56 +0200 From: Jiri Pirko <jiri@...nulli.us> To: netdev@...r.kernel.org Cc: davem@...emloft.net, idosch@...lanox.com, mlxsw@...lanox.com Subject: [patch net-next 2/2] mlxsw: spectrum_router: Set abort trap in all virtual routers From: Ido Schimmel <idosch@...lanox.com> When the abort mechanism is invoked a default route directing packets to the CPU is programmed in all the virtual routers currently in use. This can result in packet loss in case a new VRF is configured. Upon abort, program the default route in all virtual routers, whether they are in use or not. The patch is directed at net-next since post-abort fixes aren't critical and packet loss due to a missing default route will be insignificant compared to packet loss caused by the CPU port policer.
