* @brief get specified ring from MVPD for the specified target CPU.

* Supported Rings are:
* MVPD_RECORD_CP00 - MVPD_KEYWORD_PDR
* MVPD_RECORD_CP00 - MVPD_KEYWORD_PDG
* @param i_fapiTarget - cpu target
* @param i_chipletId - Chiplet ID
* @param i_ringId - Ring ID
* @param i_pRingBuf - pointer to a buffer allocated by the caller
* to receive the ring header and data.
* if NULL, the size of the min buffer required
* buffer will be returned in io_rRingBufsize
* with rc FAPI_RC_SUCCESS.
* @param io_rRingBufsize - in: size of ring buffer that caller has
* allocated
* out: number of BYTES that were copied to the
* output buffer.
* If the ring was not found, an error
* will be returned and this will be 0.
* If the output buffer is not big enough,
* an error will be returned and this will
* be the minimum size required.
* The buffer contains the CompressedScanData
* structure followed by compressed data. The
* caller does compression and decompression.
* Buffer: io_rRingBufsize returns xNN.
* byte x0 CompressedScanData structure (rs4 header)
* byte x18 compressed data (sizeof CompressedScanData is 0x18)
* byte xNN last byte of compressed data
*
* @return fapi::ReturnCode - FAPI_RC_SUCCESS if success,
* relevant error code for failure.
