It is used for routes that trap\n the packets to the CPU.\n\nThe RPF and MULTICAST traps have rate limiters as these traps may have\nline-rate of packets trapped. The PIM trap has a rate limiter similarly to\nother L3 control protocols. The rate limiters are implemented by adding\nthree new trap groups for the newly introduced traps.\n\nSigned-off-by: Yotam Gigi <yotamg@mellanox.com>\nReviewed-by: Ido Schimmel <idosch@mellanox.com>\nSigned-off-by: Jiri Pirko <jiri@mellanox.com>\n---\n drivers/net/ethernet/mellanox/mlxsw/reg.h | 3 +++\n drivers/net/ethernet/mellanox/mlxsw/spectrum.c | 10 ++++++++++\n drivers/net/ethernet/mellanox/mlxsw/trap.h | 4 ++++\n 3 files changed, 17 insertions(+)", "diff": "diff --git a/drivers/net/ethernet/mellanox/mlxsw/reg.h b/drivers/net/ethernet/mellanox/mlxsw/reg.h\nindex c203e0d..17eba19 100644\n--- a/drivers/net/ethernet/mellanox/mlxsw/reg.h\n+++ b/drivers/net/ethernet/mellanox/mlxsw/reg.h\n@@ -3681,12 +3681,15 @@ enum mlxsw_reg_htgt_trap_group {\n \tMLXSW_REG_HTGT_TRAP_GROUP_SP_IGMP,\n \tMLXSW_REG_HTGT_TRAP_GROUP_SP_BGP,\n \tMLXSW_REG_HTGT_TRAP_GROUP_SP_OSPF,\n+\tMLXSW_REG_HTGT_TRAP_GROUP_SP_PIM,\n+\tMLXSW_REG_HTGT_TRAP_GROUP_SP_MULTICAST,\n \tMLXSW_REG_HTGT_TRAP_GROUP_SP_ARP,\n \tMLXSW_REG_HTGT_TRAP_GROUP_SP_HOST_MISS,\n \tMLXSW_REG_HTGT_TRAP_GROUP_SP_ROUTER_EXP,\n \tMLXSW_REG_HTGT_TRAP_GROUP_SP_REMOTE_ROUTE,\n \tMLXSW_REG_HTGT_TRAP_GROUP_SP_IP2ME,\n \tMLXSW_REG_HTGT_TRAP_GROUP_SP_DHCP,\n+\tMLXSW_REG_HTGT_TRAP_GROUP_SP_RPF,\n \tMLXSW_REG_HTGT_TRAP_GROUP_SP_EVENT,\n \tMLXSW_REG_HTGT_TRAP_GROUP_SP_IPV6_MLD,\n \tMLXSW_REG_HTGT_TRAP_GROUP_SP_IPV6_ND,\ndiff --git a/drivers/net/ethernet/mellanox/mlxsw/spectrum.c b/drivers/net/ethernet/mellanox/mlxsw/spectrum.c\nindex 6ba6ff2..e9b9443 100644\n--- a/drivers/net/ethernet/mellanox/mlxsw/spectrum.c\n+++ b/drivers/net/ethernet/mellanox/mlxsw/spectrum.c\n@@ -3421,6 +3421,10 @@ static const struct mlxsw_listener mlxsw_sp_listener[] = {\n \t\t false, SP_IP2ME, DISCARD),\n \t/* ACL trap */\n \tMLXSW_SP_RXL_NO_MARK(ACL0, TRAP_TO_CPU, IP2ME, false),\n+\t/* Multicast Router Traps */\n+\tMLXSW_SP_RXL_MARK(IPV4_PIM, TRAP_TO_CPU, PIM, false),\n+\tMLXSW_SP_RXL_MARK(RPF, TRAP_TO_CPU, RPF, false),\n+\tMLXSW_SP_RXL_MARK(ACL1, TRAP_TO_CPU, MULTICAST, false),\n };\n \n static int mlxsw_sp_cpu_policers_set(struct mlxsw_core *mlxsw_core)\n@@ -3446,6 +3450,8 @@ static int mlxsw_sp_cpu_policers_set(struct mlxsw_core *mlxsw_core)\n \t\tcase MLXSW_REG_HTGT_TRAP_GROUP_SP_LACP:\n \t\tcase MLXSW_REG_HTGT_TRAP_GROUP_SP_LLDP:\n \t\tcase MLXSW_REG_HTGT_TRAP_GROUP_SP_OSPF:\n+\t\tcase MLXSW_REG_HTGT_TRAP_GROUP_SP_PIM:\n+\t\tcase MLXSW_REG_HTGT_TRAP_GROUP_SP_RPF:\n \t\t\trate = 128;\n \t\t\tburst_size = 7;\n \t\t\tbreak;\n@@ -3461,6 +3467,7 @@ static int mlxsw_sp_cpu_policers_set(struct mlxsw_core *mlxsw_core)\n \t\tcase MLXSW_REG_HTGT_TRAP_GROUP_SP_ROUTER_EXP:\n \t\tcase MLXSW_REG_HTGT_TRAP_GROUP_SP_REMOTE_ROUTE:\n \t\tcase MLXSW_REG_HTGT_TRAP_GROUP_SP_IPV6_ND:\n+\t\tcase MLXSW_REG_HTGT_TRAP_GROUP_SP_MULTICAST:\n \t\t\trate = 1024;\n \t\t\tburst_size = 7;\n \t\t\tbreak;\n@@ -3506,6 +3513,7 @@ static int mlxsw_sp_trap_groups_set(struct mlxsw_core *mlxsw_core)\n \t\tcase MLXSW_REG_HTGT_TRAP_GROUP_SP_LACP:\n \t\tcase MLXSW_REG_HTGT_TRAP_GROUP_SP_LLDP:\n \t\tcase MLXSW_REG_HTGT_TRAP_GROUP_SP_OSPF:\n+\t\tcase MLXSW_REG_HTGT_TRAP_GROUP_SP_PIM:\n \t\t\tpriority = 5;\n \t\t\ttc = 5;\n \t\t\tbreak;\n@@ -3522,12 +3530,14 @@ static int mlxsw_sp_trap_groups_set(struct mlxsw_core *mlxsw_core)\n \t\t\tbreak;\n \t\tcase MLXSW_REG_HTGT_TRAP_GROUP_SP_ARP:\n \t\tcase MLXSW_REG_HTGT_TRAP_GROUP_SP_IPV6_ND:\n+\t\tcase MLXSW_REG_HTGT_TRAP_GROUP_SP_RPF:\n \t\t\tpriority = 2;\n \t\t\ttc = 2;\n \t\t\tbreak;\n \t\tcase MLXSW_REG_HTGT_TRAP_GROUP_SP_HOST_MISS:\n \t\tcase MLXSW_REG_HTGT_TRAP_GROUP_SP_ROUTER_EXP:\n \t\tcase MLXSW_REG_HTGT_TRAP_GROUP_SP_REMOTE_ROUTE:\n+\t\tcase MLXSW_REG_HTGT_TRAP_GROUP_SP_MULTICAST:\n \t\t\tpriority = 1;\n \t\t\ttc = 1;\n \t\t\tbreak;\ndiff --git a/drivers/net/ethernet/mellanox/mlxsw/trap.h b/drivers/net/ethernet/mellanox/mlxsw/trap.h\nindex f396a1f..a981035 100644\n--- a/drivers/net/ethernet/mellanox/mlxsw/trap.h\n+++ b/drivers/net/ethernet/mellanox/mlxsw/trap.h\n@@ -62,6 +62,8 @@ enum {\n \tMLXSW_TRAP_ID_TTLERROR = 0x53,\n \tMLXSW_TRAP_ID_LBERROR = 0x54,\n \tMLXSW_TRAP_ID_IPV4_OSPF = 0x55,\n+\tMLXSW_TRAP_ID_IPV4_PIM = 0x58,\n+\tMLXSW_TRAP_ID_RPF = 0x5C,\n \tMLXSW_TRAP_ID_IP2ME = 0x5F,\n \tMLXSW_TRAP_ID_IPV6_UNSPECIFIED_ADDRESS = 0x60,\n \tMLXSW_TRAP_ID_IPV6_LINK_LOCAL_DEST = 0x61,\n@@ -89,6 +91,8 @@ enum {\n \tMLXSW_TRAP_ID_ROUTER_ALERT_IPV4 = 0xD6,\n \tMLXSW_TRAP_ID_ROUTER_ALERT_IPV6 = 0xD7,\n \tMLXSW_TRAP_ID_ACL0 = 0x1C0,\n+\t/* Multicast trap used for routes with trap action */\n+\tMLXSW_TRAP_ID_ACL1 = 0x1C1,\n \n \tMLXSW_TRAP_ID_MAX = 0x1FF\n };\n", "prefixes": [ "net-next", "13/13" ] }
