NAME

       mlx5dv_devx_query_eqn - Query EQN for a given vector id.

SYNOPSIS

              #include <infiniband/mlx5dv.h>

              int mlx5dv_devx_query_eqn(struct ibv_context *context, uint32_t vector,
                                        uint32_t *eqn);

DESCRIPTION

       Query EQN for a given input vector, the EQN is needed for other device commands over the DEVX interface.

       The  DEVX  API  enables  direct  access  from  the  user  space  area  to the mlx5 device driver, the EQN
       information is needed for few commands such as CQ creation.

ARGUMENTS

       context
              RDMA device context to work on.

       vector Completion vector number.

       eqn    The device EQ number which relates to the given input vector.

RETURN VALUE

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