+BBDEV FFT Operation
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+This operation allows to run a combination of DFT and/or IDFT and/or time-domain windowing.
+These can be used in a modular fashion (using bypass modes) or as a processing pipeline
+which can be used for FFT-based baseband signal processing.
+In more details it allows :
+- to process the data first through an IDFT of adjustable size and padding;
+- to perform the windowing as a programmable cyclic shift offset of the data followed by a
+pointwise multiplication by a time domain window;
+- to process the related data through a DFT of adjustable size and depadding for each such cyclic
+shift output.
+
+A flexible number of Rx antennas are being processed in parallel with the same configuration.
+The API allows more generally for flexibility in what the PMD may support (cabability 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.
+
+ **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.
+

+The mbuf input ``base_input`` is mandatory for all BBDEV PMDs and is the
+incoming data for the processing. Its size may not fit into an actual mbuf, but the
+structure is used to pass iova address.
+The mbuf output ``output`` is mandatory and is output of the FFT processing chain.
+Each point is a complex number of 32bits : either as 2 INT16 or as 2 FP16 based when the option
+supported.
+The data layout is based on contiguous concatenation of output data first by cyclic shift then
+by antenna.
