NAME¶
mlx5dv_create_flow_matcher - creates a matcher to be used with mlx5dv_create_flow(3)SYNOPSIS¶
-
#include <infiniband/mlx5dv.h> struct mlx5dv_flow_matcher * mlx5dv_create_flow_matcher(struct ibv_context *context, struct mlx5dv_flow_matcher_attr *attr)
DESCRIPTION¶
mlx5dv_create_flow_matcher() creates a flow matcher (mask) to be used with mlx5dv_create_flow(3).ARGUMENTS¶
Please see ibv_open_device(3) for context.attr¶
-
struct mlx5dv_flow_matcher_attr { enum ibv_flow_attr_type type; uint32_t flags; /* From enum ibv_flow_flags */ uint16_t priority; uint8_t match_criteria_enable; /* Device spec format */ struct mlx5dv_flow_match_parameters *match_mask; uint64_t comp_mask; };
- type
- Type of matcher to be created: IBV_FLOW_ATTR_NORMAL: Normal rule according to specification.
- flags
- special flags to control rule: 0: Nothing or zero value means matcher will store ingress flow rules. IBV_FLOW_ATTR_FLAGS_EGRESS: Specified this matcher will store egress flow rules.
- priority
- See ibv_create_flow(3).
- match_criteria_enable
- What match criteria is configured in match_mask, passed in device spec format.
match_mask¶
-
struct mlx5dv_flow_match_parameters { size_t match_sz; uint64_t match_buf[]; /* Device spec format */ };
- match_sz
- Size in bytes of match_buf.
- match_buf
- Set which mask to be used, passed in device spec format.
RETURN VALUE¶
mlx5dv_create_flow_matcher returns a pointer to mlx5dv_flow_matcher, on error NULL will be returned and errno will be set.SEE ALSO¶
