From: Kishore Padmanabha Date: Wed, 15 Apr 2020 08:19:04 +0000 (+0530) Subject: net/bnxt: support flow API create X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=82b509d346d53bb82384ddb49ecd37235aefb9cf;p=dpdk.git net/bnxt: support flow API create This patch does the following 1. Validates rte_flow_create arguments 2. Parses rte_flow_item types 3. Parses rte_flow_action types 4. Calls ulp_matcher_pattern_match to see if the flow is supported 5. If there is a match, calls ulp_mapper_flow_create to program key & action tables Signed-off-by: Kishore Padmanabha Signed-off-by: Venkat Duvvuru Reviewed-by: Lance Richardson Reviewed-by: Ajit Khaparde --- diff --git a/drivers/net/bnxt/Makefile b/drivers/net/bnxt/Makefile index 5e2d751ab5..5ed33ccbf1 100644 --- a/drivers/net/bnxt/Makefile +++ b/drivers/net/bnxt/Makefile @@ -65,6 +65,7 @@ SRCS-$(CONFIG_RTE_LIBRTE_BNXT_PMD) += tf_ulp/ulp_utils.c SRCS-$(CONFIG_RTE_LIBRTE_BNXT_PMD) += tf_ulp/ulp_mapper.c SRCS-$(CONFIG_RTE_LIBRTE_BNXT_PMD) += tf_ulp/ulp_matcher.c SRCS-$(CONFIG_RTE_LIBRTE_BNXT_PMD) += tf_ulp/ulp_rte_parser.c +SRCS-$(CONFIG_RTE_LIBRTE_BNXT_PMD) += tf_ulp/bnxt_ulp_flow.c # # Export include files diff --git a/drivers/net/bnxt/tf_ulp/bnxt_ulp_flow.c b/drivers/net/bnxt/tf_ulp/bnxt_ulp_flow.c new file mode 100644 index 0000000000..6402dd3f62 --- /dev/null +++ b/drivers/net/bnxt/tf_ulp/bnxt_ulp_flow.c @@ -0,0 +1,177 @@ +/* SPDX-License-Identifier: BSD-3-Clause + * Copyright(c) 2014-2020 Broadcom + * All rights reserved. + */ + +#include "bnxt.h" +#include "bnxt_tf_common.h" +#include "ulp_rte_parser.h" +#include "ulp_matcher.h" +#include "ulp_flow_db.h" +#include "ulp_mapper.h" +#include + +static int32_t +bnxt_ulp_flow_validate_args(const struct rte_flow_attr *attr, + const struct rte_flow_item pattern[], + const struct rte_flow_action actions[], + struct rte_flow_error *error) +{ + /* Perform the validation of the arguments for null */ + if (!error) + return BNXT_TF_RC_ERROR;
