This\ncan result in packet loss in case a new VRF is configured.\n\nUpon abort, program the default route in all virtual routers, whether\nthey are in use or not.\n\nThe patch is directed at net-next since post-abort fixes aren't critical\nand packet loss due to a missing default route will be insignificant\ncompared to packet loss caused by the CPU port policer.\n\nSigned-off-by: Ido Schimmel <idosch@mellanox.com>\nSigned-off-by: Jiri Pirko <jiri@mellanox.com>\n---\n drivers/net/ethernet/mellanox/mlxsw/spectrum_router.c | 3 ---\n 1 file changed, 3 deletions(-)",
