The API allows more generally for flexibility in what the PMD may support (capability flags) and
flexibility to adjust some of the parameters of the processing.
The operation/capability flags that can be set for each FFT operation are given below.
The structure passed for each FFT operation is given below,
with the operation flags forming a bitmask in the ``op_flags`` field.
**NOTE:** The actual operation flags that may be used with a specific
bbdev PMD are dependent on the driver capabilities as reported via
``rte_bbdev_info_get()``, and may be a subset of those below.
