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.
