NAME
       efadv_query_qp_wqs - Query EFA specific Queue Pair work queue
       attributes

SYNOPSIS
              #include <infiniband/efadv.h>

              int efadv_query_qp_wqs(struct ibv_qp *ibvqp, struct efadv_wq_attr *sq_attr,
                                     struct efadv_wq_attr *rq_attr, uint32_t inlen);

DESCRIPTION
       efadv_query_qp_wqs() queries device-specific Queue Pair work queue
       attributes.

       Compatibility is handled using the comp_mask and inlen fields.

              struct efadv_wq_attr {
                  uint64_t comp_mask;
                  uint8_t *buffer;
                  uint32_t entry_size;
                  uint32_t num_entries;
                  uint32_t *doorbell;
                  uint32_t max_batch;
                  uint8_t reserved[4];
              };

       inlen  In: Size of struct efadv_wq_attr.

       comp_mask
              Compatibility mask.

       buffer Queue buffer.

       entry_size
              Size of each entry in the queue.

       num_entries
              Maximal number of entries in the queue.

       doorbell
              Queue doorbell.

       max_batch
              Maximum batch size for queue submissions.

RETURN VALUE
       efadv_query_qp_wqs() returns 0 on success, or the value of errno on
       failure (which indicates the failure reason).

NOTES
       o Compatibility mask (comp_mask) is an out field and currently has no
         values.
