This patch implements this offload\ncapability in the mlx5 PMD.\n\nSigned-off-by: Moti Haimovsky <motih@mellanox.com>\n---\nNote:\n This patch should be applied on top of the new flow engine commits\n by orika and yskoh\n---\n drivers/net/mlx5/Makefile | 10 ++++++++++\n drivers/net/mlx5/mlx5_flow.c | 9 ++++++++-\n drivers/net/mlx5/mlx5_flow_tcf.c | 19 +++++++++++++++++++\n 3 files changed, 37 insertions(+), 1 deletion(-)", "diff": "diff --git a/drivers/net/mlx5/Makefile b/drivers/net/mlx5/Makefile\nindex ca1de9f..9097456 100644\n--- a/drivers/net/mlx5/Makefile\n+++ b/drivers/net/mlx5/Makefile\n@@ -342,6 +342,16 @@ mlx5_autoconf.h.new: $(RTE_SDK)/buildtools/auto-config-h.sh\n \t\tenum TCA_FLOWER_KEY_VLAN_ETH_TYPE \\\n \t\t$(AUTOCONF_OUTPUT)\n \t$Q sh -- '$<' '$@' \\\n+\t\tHAVE_TCA_FLOWER_KEY_TCP_FLAGS \\\n+\t\tlinux/pkt_cls.h \\\n+\t\tenum TCA_FLOWER_KEY_TCP_FLAGS \\\n+\t\t$(AUTOCONF_OUTPUT)\n+\t$Q sh -- '$<' '$@' \\\n+\t\tHAVE_TCA_FLOWER_KEY_TCP_FLAGS_MASK \\\n+\t\tlinux/pkt_cls.h \\\n+\t\tenum TCA_FLOWER_KEY_TCP_FLAGS_MASK \\\n+\t\t$(AUTOCONF_OUTPUT)\n+\t$Q sh -- '$<' '$@' \\\n \t\tHAVE_TC_ACT_VLAN \\\n \t\tlinux/tc_act/tc_vlan.h \\\n \t\tenum TCA_VLAN_PUSH_VLAN_PRIORITY \\\ndiff --git a/drivers/net/mlx5/mlx5_flow.c b/drivers/net/mlx5/mlx5_flow.c\nindex f9a64d3..c8cc8fe 100644\n--- a/drivers/net/mlx5/mlx5_flow.c\n+++ b/drivers/net/mlx5/mlx5_flow.c\n@@ -1241,6 +1241,13 @@ int mlx5_flow_validate_item_tcp(uint64_t item_flags,\n \t\t\t\tstruct rte_flow_error *error)\n {\n \tconst struct rte_flow_item_tcp *mask = item->mask;\n+\tconst struct rte_flow_item_tcp nic_mask = {\n+\t\t.hdr = {\n+\t\t\t.src_port = RTE_BE16(0xffff),\n+\t\t\t.dst_port = RTE_BE16(0xffff),\n+\t\t\t.tcp_flags = 0xff,\n+\t\t},\n+\t};\n \tconst int tunnel = !!(item_flags & MLX5_FLOW_LAYER_TUNNEL);\n \tint ret;\n \n@@ -1266,7 +1273,7 @@ int mlx5_flow_validate_item_tcp(uint64_t item_flags,\n \t\tmask = &rte_flow_item_tcp_mask;\n \tret = mlx5_flow_item_acceptable\n \t\t(item, (const uint8_t *)mask,\n-\t\t (const uint8_t *)&rte_flow_item_tcp_mask,\n+\t\t (const uint8_t *)&nic_mask,\n \t\t sizeof(struct rte_flow_item_tcp), error);\n \tif (ret < 0)\n \t\treturn ret;\ndiff --git a/drivers/net/mlx5/mlx5_flow_tcf.c b/drivers/net/mlx5/mlx5_flow_tcf.c\nindex 769a13a..5034862 100644\n--- a/drivers/net/mlx5/mlx5_flow_tcf.c\n+++ b/drivers/net/mlx5/mlx5_flow_tcf.c\n@@ -148,6 +148,12 @@ struct tc_vlan {\n #ifndef HAVE_TCA_FLOWER_KEY_VLAN_ETH_TYPE\n #define TCA_FLOWER_KEY_VLAN_ETH_TYPE 25\n #endif\n+#ifndef TCA_FLOWER_KEY_TCP_FLAGS\n+#define TCA_FLOWER_KEY_TCP_FLAGS 71\n+#endif\n+#ifndef TCA_FLOWER_KEY_TCP_FLAGS_MASK\n+#define TCA_FLOWER_KEY_TCP_FLAGS_MASK 72\n+#endif\n \n #ifndef IPV6_ADDR_LEN\n #define IPV6_ADDR_LEN 16\n@@ -204,6 +210,7 @@ struct tc_vlan {\n \t.tcp.hdr = {\n \t\t.src_port = RTE_BE16(0xffff),\n \t\t.dst_port = RTE_BE16(0xffff),\n+\t\t.tcp_flags = 0xff,\n \t},\n \t.udp.hdr = {\n \t\t.src_port = RTE_BE16(0xffff),\n@@ -1271,6 +1278,18 @@ struct flow_tcf_ptoi {\n \t\t\t\t\t\t TCA_FLOWER_KEY_TCP_DST_MASK,\n \t\t\t\t\t\t mask.tcp->hdr.dst_port);\n \t\t\t}\n+\t\t\tif (mask.tcp->hdr.tcp_flags) {\n+\t\t\t\tmnl_attr_put_u16\n+\t\t\t\t\t(nlh,\n+\t\t\t\t\t TCA_FLOWER_KEY_TCP_FLAGS,\n+\t\t\t\t\t rte_cpu_to_be_16\n+\t\t\t\t\t\t(spec.tcp->hdr.tcp_flags));\n+\t\t\t\tmnl_attr_put_u16\n+\t\t\t\t\t(nlh,\n+\t\t\t\t\t TCA_FLOWER_KEY_TCP_FLAGS_MASK,\n+\t\t\t\t\t rte_cpu_to_be_16\n+\t\t\t\t\t\t(mask.tcp->hdr.tcp_flags));\n+\t\t\t}\n \t\t\tbreak;\n \t\tdefault:\n \t\t\treturn rte_flow_error_set(error, ENOTSUP,\n", "prefixes": [] }
