* @param [IN]pPacket - Packet buffer containing the packet to parse
* @param [OUT]pPktSizeByType - Size of the packet as determined by its type and other parameters
* @param [IN]pktBufferSize - Size of the packet buffer provided. Sensor Data packet buffer can
* have multiple HIF packets. In case of Sensor Control packets, the buffer is expected
* to contain only one packet.
*
* @return OSP_STATUS_OK or Error code enum corresponding to the error encountered
