Like Ethernet,\nIB defines a layered protocol (Physical, Link, Network, Transport\nLayers). IB provides native support for RDMA(Remote DMA), an\nextension of the DMA that allows direct access to remote host\nmemory without CPU intervention. IB network requires NICs and\nswitches to support the IB protocol.\n\nRoCE(RDMA over Converged Ethernet) is a network protocol that\nallows RDMA to run on Ethernet. RoCE encapsulates IB packets on\nethernet and has two versions, RoCEv1 and RoCEv2. RoCEv1 is an\nethernet link layer protocol, IB packets are encapsulated in the\nethernet layer and use ethernet type 0x8915. RoCEv2 is an internet\nlayer protocol, IB packets are encapsulated in UDP payload and\nuse a destination port 4791, The format of the RoCEv2 packet is\nas follows:\n ETH + IP + UDP(dport 4791) + IB(BTH + ExtHDR + PAYLOAD + CRC)\n\nBTH(Base Transport Header) is the IB transport layer header, RoCEv1\nand RoCEv2 both contain this header. This patch introduces a new\nRTE item to match the IB BTH in RoCE packets. One use of this match\nis that the user can monitor RoCEv2's CNP(Congestion Notification\nPacket) by matching BTH opcode 0x81.\n\nThis patch also adds the testpmd command line to match the RoCEv2\nBTH. Usage example:\n\n testpmd> flow create 0 group 1 ingress pattern\n eth / ipv4 / udp dst is 4791 / ib_bth opcode is 0x81\n dst_qp is 0xd3 / end actions queue index 0 / end\n\nSigned-off-by: Dong Zhou <dongzhou@nvidia.com>\n---\n app/test-pmd/cmdline_flow.c | 58 ++++++++++++++++++\n doc/guides/nics/features/default.ini | 1 +\n doc/guides/prog_guide/rte_flow.rst | 7 +++\n doc/guides/testpmd_app_ug/testpmd_funcs.rst | 6 ++\n lib/ethdev/rte_flow.c | 1 +\n lib/ethdev/rte_flow.h | 27 ++++++++\n lib/net/rte_ib.h | 68 +++++++++++++++++++++\n 7 files changed, 168 insertions(+)\n create mode 100644 lib/net/rte_ib.h", "diff": "diff --git a/app/test-pmd/cmdline_flow.c b/app/test-pmd/cmdline_flow.c\nindex 5fbc450849..3ff33b281d 100644\n--- a/app/test-pmd/cmdline_flow.c\n+++ b/app/test-pmd/cmdline_flow.c\n@@ -531,6 +531,11 @@ enum index {\n \tITEM_QUOTA_STATE_NAME,\n \tITEM_PORT_AFFINITY,\n \tITEM_PORT_AFFINITY_VALUE,\n+\tITEM_IB_BTH,\n+\tITEM_IB_BTH_OPCODE,\n+\tITEM_IB_BTH_PKEY,\n+\tITEM_IB_BTH_DST_QPN,\n+\tITEM_IB_BTH_PSN,\n \n \t/* Validate/create actions. */\n \tACTIONS,\n@@ -1517,6 +1522,7 @@ static const enum index next_item[] = {\n \tITEM_QUOTA,\n \tITEM_PORT_AFFINITY,\n \tITEM_IPSEC_SYNDROME,\n+\tITEM_IB_BTH,\n \tEND_SET,\n \tZERO,\n };\n@@ -2025,6 +2031,15 @@ static const enum index item_ipsec_syndrome[] = {\n \tZERO,\n };\n \n+static const enum index item_ib_bth[] = {\n+\tITEM_IB_BTH_OPCODE,\n+\tITEM_IB_BTH_PKEY,\n+\tITEM_IB_BTH_DST_QPN,\n+\tITEM_IB_BTH_PSN,\n+\tITEM_NEXT,\n+\tZERO,\n+};\n+\n static const enum index next_action[] = {\n \tACTION_END,\n \tACTION_VOID,\n@@ -5750,6 +5765,46 @@ static const struct token token_list[] = {\n \t\t.args = ARGS(ARGS_ENTRY(struct mlx5_flow_item_ipsec_syndrome,\n \t\t\t\t\tsyndrome)),\n \t},\n+\t[ITEM_IB_BTH] = {\n+\t\t.name = \"ib_bth\",\n+\t\t.help = \"match ib bth fields\",\n+\t\t.priv = PRIV_ITEM(IB_BTH,\n+\t\t\t\t sizeof(struct rte_flow_item_ib_bth)),\n+\t\t.next = NEXT(item_ib_bth),\n+\t\t.call = parse_vc,\n+\t},\n+\t[ITEM_IB_BTH_OPCODE] = {\n+\t\t.name = \"opcode\",\n+\t\t.help = \"match ib bth opcode\",\n+\t\t.next = NEXT(item_ib_bth, NEXT_ENTRY(COMMON_UNSIGNED),\n+\t\t\t\t item_param),\n+\t\t.args = ARGS(ARGS_ENTRY_HTON(struct rte_flow_item_ib_bth,\n+\t\t\t\t\t\t hdr.opcode)),\n+\t},\n+\t[ITEM_IB_BTH_PKEY] = {\n+\t\t.name = \"pkey\",\n+\t\t.help = \"partition key\",\n+\t\t.next = NEXT(item_ib_bth, NEXT_ENTRY(COMMON_UNSIGNED),\n+\t\t\t\t item_param),\n+\t\t.args = ARGS(ARGS_ENTRY_HTON(struct rte_flow_item_ib_bth,\n+\t\t\t\t\t\t hdr.pkey)),\n+\t},\n+\t[ITEM_IB_BTH_DST_QPN] = {\n+\t\t.name = \"dst_qp\",\n+\t\t.help = \"destination qp\",\n+\t\t.next = NEXT(item_ib_bth, NEXT_ENTRY(COMMON_UNSIGNED),\n+\t\t\t\t item_param),\n+\t\t.args = ARGS(ARGS_ENTRY_HTON(struct rte_flow_item_ib_bth,\n+\t\t\t\t\t\t hdr.dst_qp)),\n+\t},\n+\t[ITEM_IB_BTH_PSN] = {\n+\t\t.name = \"psn\",\n+\t\t.help = \"packet sequence number\",\n+\t\t.next = NEXT(item_ib_bth, NEXT_ENTRY(COMMON_UNSIGNED),\n+\t\t\t\t item_param),\n+\t\t.args = ARGS(ARGS_ENTRY_HTON(struct rte_flow_item_ib_bth,\n+\t\t\t\t\t\t hdr.psn)),\n+\t},\n \t/* Validate/create actions. */\n \t[ACTIONS] = {\n \t\t.name = \"actions\",\n@@ -12634,6 +12689,9 @@ flow_item_default_mask(const struct rte_flow_item *item)\n \tcase RTE_FLOW_ITEM_TYPE_IPV6_ROUTING_EXT:\n \t\tmask = &ipv6_routing_ext_default_mask;\n \t\tbreak;\n+\tcase RTE_FLOW_ITEM_TYPE_IB_BTH:\n+\t\tmask = &rte_flow_item_ib_bth_mask;\n+\t\tbreak;\n \tdefault:\n \t\tbreak;\n \t}\ndiff --git a/doc/guides/nics/features/default.ini b/doc/guides/nics/features/default.ini\nindex 510cc6679d..54045a29a0 100644\n--- a/doc/guides/nics/features/default.ini\n+++ b/doc/guides/nics/features/default.ini\n@@ -103,6 +103,7 @@ gtpc =\n gtpu =\n gtp_psc =\n higig2 =\n+ib_bth =\n icmp =\n icmp6 =\n icmp6_nd_na =\ndiff --git a/doc/guides/prog_guide/rte_flow.rst b/doc/guides/prog_guide/rte_flow.rst\nindex 1d81334e96..363bbdd5d8 100644\n--- a/doc/guides/prog_guide/rte_flow.rst\n+++ b/doc/guides/prog_guide/rte_flow.rst\n@@ -1574,6 +1574,13 @@ Matches ipv6 routing extension header.\n -
