Extend the function to support all these\nuses, and allow finely-grained configuration of what should happen at\neach call through a suite of function arguments.\n\nPublish the updated function to allow use from the spectrum_ipip module.\n\nSigned-off-by: Petr Machata <petrm@mellanox.com>\nReviewed-by: Ido Schimmel <idosch@mellanox.com>\nSigned-off-by: Jiri Pirko <jiri@mellanox.com>\n---\n .../net/ethernet/mellanox/mlxsw/spectrum_router.c | 47 ++++++++++++++++++++--\n .../net/ethernet/mellanox/mlxsw/spectrum_router.h | 7 ++++\n 2 files changed, 50 insertions(+), 4 deletions(-)", "diff": "diff --git a/drivers/net/ethernet/mellanox/mlxsw/spectrum_router.c b/drivers/net/ethernet/mellanox/mlxsw/spectrum_router.c\nindex e2795b8..1376a97 100644\n--- a/drivers/net/ethernet/mellanox/mlxsw/spectrum_router.c\n+++ b/drivers/net/ethernet/mellanox/mlxsw/spectrum_router.c\n@@ -1355,9 +1355,12 @@ static void mlxsw_sp_netdevice_ipip_ol_down_event(struct mlxsw_sp *mlxsw_sp,\n \t\tmlxsw_sp_ipip_entry_ol_down_event(mlxsw_sp, ipip_entry);\n }\n \n+static void mlxsw_sp_nexthop_rif_update(struct mlxsw_sp *mlxsw_sp,\n+\t\t\t\t\tstruct mlxsw_sp_rif *rif);\n static int\n mlxsw_sp_ipip_entry_ol_lb_update(struct mlxsw_sp *mlxsw_sp,\n \t\t\t\t struct mlxsw_sp_ipip_entry *ipip_entry,\n+\t\t\t\t bool keep_encap,\n \t\t\t\t struct netlink_ext_ack *extack)\n {\n \tstruct mlxsw_sp_rif_ipip_lb *old_lb_rif = ipip_entry->ol_lb;\n@@ -1370,13 +1373,32 @@ mlxsw_sp_ipip_entry_ol_lb_update(struct mlxsw_sp *mlxsw_sp,\n \tif (IS_ERR(new_lb_rif))\n \t\treturn PTR_ERR(new_lb_rif);\n \tipip_entry->ol_lb = new_lb_rif;\n+\n+\tif (keep_encap) {\n+\t\tlist_splice_init(&old_lb_rif->common.nexthop_list,\n+\t\t\t\t &new_lb_rif->common.nexthop_list);\n+\t\tmlxsw_sp_nexthop_rif_update(mlxsw_sp, &new_lb_rif->common);\n+\t}\n+\n \tmlxsw_sp_rif_destroy(&old_lb_rif->common);\n \n \treturn 0;\n }\n \n+/**\n+ * Update the offload related to an IPIP entry.
