ibv_create_rwq_ind_table() creates a RWQ IND TBL associated with the ibv_context context. The argument init_attr is an ibv_rwq_ind_table_init_attr struct, as defined in <infiniband/verbs.h>. struct ibv_rwq_ind_table_init_attr { uint32_t log_ind_tbl_size; /* Log, base 2, of Indirection table size */ struct ibv_wq **ind_tbl; /* Each entry is a pointer to Receive Work Queue */ uint32_t comp_mask; /* Identifies valid fields. Use ibv_ind_table_init_attr_mask */ }; The function ibv_create_rwq_ind_table() will create a RWQ IND TBL that holds a table of Receive Work Queue. For further usage of the created object see below NOTES. ibv_destroy_rwq_ind_table() destroys the RWQ IND TBL rwq_ind_table.

ibv_create_rwq_ind_table, ibv_destroy_rwq_ind_table - create or destroy a Receive Work Queue Indirection Table (RWQ IND TBL).

The created object should be used as part of ibv_create_qp_ex() to enable dispatching of incoming packets based on some RX hash configuration.

ibv_create_rwq_ind_table() returns a pointer to the created RWQ IND TBL, or NULL if the request fails. ibv_destroy_rwq_ind_table() returns 0 on success, or the value of errno on failure (which indicates the failure reason).
