NAME

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

SYNOPSIS

       #include <infiniband/verbs.h>

       struct ibv_rwq_ind_table *ibv_create_rwq_ind_table(struct ibv_context *context,
                                                                  struct ibv_rwq_ind_table_init_attr *init_attr);

       int ibv_destroy_rwq_ind_table(struct ibv_rwq_ind_table *rwq_ind_table);

DESCRIPTION

       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.

RETURN VALUE

       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).

NOTES

       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.
