+ * BIG NOTE on DOUBLE BUFFERING.
+ *
+ * In order to extract data from the ring buffer, protected by spinlocks,
+ * to user space we use a double buffer: data is so finally copied to
+ * userspace from a temporary double buffer, after having copied into it
+ * ALL the desired content and after all the spinlocks have been released.
+ * In order to avoid use of an additional mutex to protect such temporary
+ * buffer from multiple readers access we use a oneshot throwaway buffer
+ * dedicated to each reader and allocated at opening time.
+ * The most straightforward way to do this thing would have been to simply
+ * allocate such buffer inside the read method and throw it away on exit:
+ * this is what underlying printk mechanism does via a simple kmalloc.
+ * BUT we decided INSTEAD to use this buffer ALSO as a sort of caching
+ * area for each reader in order to cope with under-sized user read-request;
+ * basically no matter what the user has asked in term of size of the read
+ * request we'll ALWAYS RETRIEVE multiple of whole records from the ring,
+ * one record being the minimum internal ring-read-request this way.
+ * So no matter if the user ask for a few bytes, less than the next record
+ * size, we'll retrieve ONE WHOLE record from the ring into the double buffer:
+ * this way on the next read request we'll have already a cached copy of the
+ * record and we could deal with it inside the read callback without the
+ * need to access the ring anymore for such record.
+ * The main reason for this is that if we had instead accessed the ring and
+ * retrieved ONLY a fraction of the record, on the next request we could NOT
+ * be able to provide the remaining part of the record because, being the ring
+ * an overwriting buffer, it could have wrap in the meantime and we could have
+ * simply lost that data: this condition would have lead us to return to
+ * user partial truncated records when we hit this overwrap condition.
+ * Following instead the approach of WHOLE records retrieval we can instead be
+ * sure to always retrieve fully correct records, despite being vulnerable
+ * anyway to loss of data (whole records) while reading if fast writers
+ * overwrite our data. (since we'll never ever want to slow down and starve a
+ * writer.)

+ *  SC-507780-DD --  Android Enhanced Logging
+ *                  WiFiLogger Core Driver Requirements and Design
+ *
+ * This is the CONSUMER API as implemented by scsc_wifilogger driver:
+ * the framework and WiFi HAL are the final consumer of WiFi logger provided
+ * data but this API is directly used by our driver NetLink layer to
+ * configure and start/stop Android Enhanced Logging - WiFi Logger.
+ *
+ * Workflow is as follows:
+ *
+ *  - framework invokes wifi_logger.h exported methods implemented by WiFi HAL
+ *  - WiFi HAL wifi_logger module translates wifi_logger.h requests into
+ *    NetLink vendor messages dispatched to out driver
+ *  - our SCSC netlink layer driver translates back NetLink received messages
+ *    into invokations of methods exported by this driver into the current
+ *    header file
+ *  - this driver, manages all the basic ring operations, providing:
+ *     + this consumer API used to configure and start/stop the data-consuming
+ *       reader-process that pushes data up to the framework through the NetLink
+ *       channel
+ *     + a producer API that will be used to push data/record into the rings
+ *     + all the machinery needed to create and manage multiple rings
+ *

+ * General Ring Architecture
+ * -------------------------
+ * The ring is constituted by a buffer of contiguos memory of specified
+ * size followed by a spare area of MAX_RECORD_SZ; this latter area is used
+ * when a record would not fit the physical end of the ring buffer and would
+ * be going to wrap around: in a such a case we simply write down the record
+ * content and let it spill over into the spare area; we'll then take care
+ * to copy the overflown part from the spare area into the start of the
+ * physical buffer. For this reason a limit of MAX_RECORD_SZ length is
+ * enforced on write.
+ *
+ * Ring status is maintained inside <struct scsc_wifi_ring_buffer_status> that
+ * is a well known and defined structure defined in scsc_wifilogger_types.h;
+ * such structure format is expected by Framework itself when it queries for
+ * ring status using Wi-Fi HAL.
+ * Such structure contains also the @read_bytes and @written_bytes counters
+ * needed for all the ring mechanics based on modulo-ring-size aritmethic.
+ * Modulo arithmethic is achieved without using the % operator itself so ring
+ * is expected to be of power-of-two size.
+ *
+ * Ring's basic operations are defined as follows:
+ * - MULTIPLE concurrent writers are expected (and handled)
+ *
+ * - Only ONE active reader is expected at any time: such a reader could act
+ *   out of the periodic reader worker or triggered by a write operation.
+ *
+ * - each ring read-behavior is configured by two params:
+ *   + min_data_size: the minimum amount of available data that should trigger
+ *     a read. Ignored if zero.
+ *   + max_interval_sec: periodic-reader interval in seconds. Ignored if zero.
+ *
+ * NOTE THAT if both the above params are configured as zero, no periodic or
+ * threshold reading process will be performed and, in absence of any kind of
+ * polling-read mechanism, the ring would finally FILL-UP: in such a case all
+ * the data received once the ring is full will be DROPPED.
+ * This behavior fits the pkt_fate use case scenario.
