/*
 * Rx SRAM Control and Status Registers (RSCSR)
 *
 * These registers provide handshake between driver and Shirley Peak for
 * the Rx queue
 * (this queue handles *all* command responses, notifications, Rx data, etc.
 * sent from SP uCode to host driver).  Unlike Tx, there is only one Rx
 * queue, and only one Rx DMA/FIFO channel.  Also unlike Tx, which can
 * concatenate up to 20 DRAM buffers to form a Tx frame, each Receive Buffer
 * Descriptor (RBD) points to only one Rx Buffer (RB); there is a 1:1
 * mapping between RBDs and RBs.
 *
 * Driver must allocate host DRAM memory for the following, and set the
 * physical address of each into SP registers:
 *
 * 1)  Receive Buffer Descriptor (RBD) circular buffer (CB), typically with 256
 *     entries (although any power of 2, up to 4096, is selectable by driver).
 *     Each entry (1 dword) points to a receive buffer (RB) of consistent size
 *     (typically 4K, although 8K or 16K are also selectable by driver).
 *     Driver sets up RB size and number of RBDs in the CB via Rx config
 *     register FH_MEM_RCSR_CHNL0_CONFIG_REG.
 *
 *     Bit fields within one RBD:
 *     27-0:  Receive Buffer physical address bits [35:8], 256-byte aligned.
 *
 *     Driver sets physical address [35:8] of base of RBD circular buffer
 *     into FH_RSCSR_CHNL0_RBDCB_BASE_REG [27:0].
 *
 * 2)  Rx status buffer, 8 bytes, in which SP indicates which Rx Buffers
 *     (RBs) have been filled, via a "write pointer", actually the index of
 *     the RB's corresponding RBD within the circular buffer.  Driver sets
 *     physical address [35:4] into FH_RSCSR_CHNL0_STTS_WPTR_REG [31:0].
 *
 *     Bit fields in lower dword of Rx status buffer (upper dword not used
 *     by driver; see struct iwp_shared, val0):
 *     31-12:  Not used by driver
 *     11- 0:  Index of last filled Rx buffer descriptor
 *             (SP writes, driver reads this value)
 *
 * As the driver prepares Receive Buffers (RBs) for SP to fill, driver must
 * enter pointers to these RBs into contiguous RBD circular buffer entries,
 * and update the SP's "write" index register, FH_RSCSR_CHNL0_RBDCB_WPTR_REG.
 *
 * This "write" index corresponds to the *next* RBD that the driver will make
 * available, i.e. one RBD past the the tail of the ready-to-fill RBDs within
 * the circular buffer.  This value should initially be 0 (before preparing any
 * RBs), should be 8 after preparing the first 8 RBs (for example), and must
 * wrap back to 0 at the end of the circular buffer (but don't wrap before
 * "read" index has advanced past 1!  See below).
 * NOTE:  SP EXPECTS THE WRITE INDEX TO BE INCREMENTED IN MULTIPLES OF 8.
 *
 * As the SP fills RBs (referenced from contiguous RBDs within the circular
 * buffer), it updates the Rx status buffer in DRAM, 2) described above,
 * to tell the driver the index of the latest filled RBD.  The driver must
 * read this "read" index from DRAM after receiving an Rx interrupt from SP.
 *
 * The driver must also internally keep track of a third index, which is the
 * next RBD to process.  When receiving an Rx interrupt, driver should process
 * all filled but unprocessed RBs up to, but not including, the RB
 * corresponding to the "read" index.  For example, if "read" index becomes "1",
 * driver may process the RB pointed to by RBD 0.  Depending on volume of
 * traffic, there may be many RBs to process.
 *
 * If read index == write index, SP thinks there is no room to put new data.
 * Due to this, the maximum number of filled RBs is 255, instead of 256.  To
 * be safe, make sure that there is a gap of at least 2 RBDs between "write"
 * and "read" indexes; that is, make sure that there are no more than 254
 * buffers waiting to be filled.

/*
 * Tx Scheduler
 *
 * The Tx Scheduler selects the next frame to be transmitted, chosing TFDs
 * (Transmit Frame Descriptors) from up to 16 circular queues resident in
 * host DRAM.  It steers each frame's Tx command (which contains the frame
 * data) through one of up to 7 prioritized Tx DMA FIFO channels within the
 * device.  A queue maps to only one (selectable by driver) Tx DMA channel,
 * but one DMA channel may take input from several queues.
 *
 * Tx DMA channels have dedicated purposes.  For SP, and are used as follows:
 * BMC TODO:  CONFIRM channel assignments, esp for 0/1
 *
 * 0 -- EDCA BK (background) frames, lowest priority
 * 1 -- EDCA BE (best effort) frames, normal priority
 * 2 -- EDCA VI (video) frames, higher priority
 * 3 -- EDCA VO (voice) and management frames, highest priority
 * 4 -- Commands (e.g. RXON, etc.)
 * 5 -- HCCA short frames
 * 6 -- HCCA long frames
 * 7 -- not used by driver (device-internal only)
 *
 * Driver should normally map queues 0-6 to Tx DMA/FIFO channels 0-6.
 * In addition, driver can map queues 7-15 to Tx DMA/FIFO channels 0-3 to
 * support 11n aggregation via EDCA DMA channels. BMC confirm.
 *
 * The driver sets up each queue to work in one of two modes:
 *
 * 1)  Scheduler-Ack, in which the scheduler automatically supports a
 *     block-ack (BA) window of up to 64 TFDs.  In this mode, each queue
 *     contains TFDs for a unique combination of Recipient Address (RA)
 *     and Traffic Identifier (TID), that is, traffic of a given
 *     Quality-Of-Service (QOS) priority, destined for a single station.
 *
 *     In scheduler-ack mode, the scheduler keeps track of the Tx status of
 *     each frame within the BA window, including whether it's been transmitted,
 *     and whether it's been acknowledged by the receiving station.  The device
 *     automatically processes block-acks received from the receiving STA,
 *     and reschedules un-acked frames to be retransmitted (successful
 *     Tx completion may end up being out-of-order).
 *
 *     The driver must maintain the queue's Byte Count table in host DRAM
 *     (struct iwp_sched_queue_byte_cnt_tbl) for this mode.
 *     This mode does not support fragmentation.
 *
 * 2)  FIFO (a.k.a. non-Scheduler-ACK), in which each TFD is processed in order.
 *     The device may automatically retry Tx, but will retry only one frame
 *     at a time, until receiving ACK from receiving station, or reaching
 *     retry limit and giving up.
 *
 *     The command queue (#4) must use this mode!
 *     This mode does not require use of the Byte Count table in host DRAM.
 *
 * Driver controls scheduler operation via 3 means:
 * 1)  Scheduler registers
 * 2)  Shared scheduler data base in internal 4956 SRAM
 * 3)  Shared data in host DRAM
 *
 * Initialization:
 *
 * When loading, driver should allocate memory for:
 * 1)  16 TFD circular buffers, each with space for (typically) 256 TFDs.
 * 2)  16 Byte Count circular buffers in 16 KBytes contiguous memory
 *     (1024 bytes for each queue).
 *
 * After receiving "Alive" response from uCode, driver must initialize
 * the following (especially for queue #4, the command queue, otherwise
 * the driver can't issue commands!):
 *
 * 1)  SP's scheduler data base area in SRAM:
 *     a)  Read SRAM address of data base area from SCD_SRAM_BASE_ADDR
 *     b)  Clear and Init SCD_CONTEXT_DATA_OFFSET area (size 128 bytes)
 *     c)  Clear SCD_TX_STTS_BITMAP_OFFSET area (size 256 bytes)
 *     d)  Clear (BMC and init?) SCD_TRANSLATE_TBL_OFFSET (size 32 bytes)
 *
 * 2)  Init SCD_DRAM_BASE_ADDR with physical base of Tx byte count circular
 *     buffer array, allocated by driver in host DRAM.
 *
 * 3)

 * Tx/Rx Queues
 *
 * Most communication between driver and SP is via queues of data buffers.
 * For example, all commands that the driver issues to device's embedded
 * controller (uCode) are via the command queue (one of the Tx queues).  All
 * uCode command responses/replies/notifications, including Rx frames, are
 * conveyed from uCode to driver via the Rx queue.
 *
 * Most support for these queues, including handshake support, resides in
 * structures in host DRAM, shared between the driver and the device.  When
 * allocating this memory, the driver must make sure that data written by
 * the host CPU updates DRAM immediately (and does not get "stuck" in CPU's
 * cache memory), so DRAM and cache are consistent, and the device can
 * immediately see changes made by the driver.
 *
 * SP supports up to 16 DRAM-based Tx queues, and services these queues via
 * up to 7 DMA channels (FIFOs).  Each Tx queue is supported by a circular array
 * in DRAM containing 256 Transmit Frame Descriptors (TFDs).

/*
 * Hardware rate scaling set by iwp_ap_lq function.
 * Given a particular initial rate and mode, the driver uses the
 * following formula to fill the rs_table[LINK_QUAL_MAX_RETRY_NUM]
 * rate table in the Link Quality command:
 *
 * 1) If using High-throughput(HT)(SISO or MIMO) initial rate:
 *    a) Use this same initial rate for first 3 entries.
 *    b) Find next lower available rate using same mode(SISO or MIMO),
 *	 use for next 3 entries. If no lower rate available, switch to
 *	 legacy mode(no FAT channel, no MIMO, no short guard interval).
 *    c) If using MIMO, set command's mimo_delimeter to number of
 *	 entries using MIMO(3 or 6).
 *    d) After trying 2 HT rates, switch to legacy mode(no FAT channel,
 *	 no MIMO, no short qguard interval), at the next lower bit rate
 *	 (e.g. if second HT bit rate was 54, try 48 legacy),and follow
 *   legacy procedure for remaining table entries.
 *
 * 2) If using legacy initial rate:
 *    a) Use the initial rate for only one entry.
 *    b) For each following entry, reduce the rate to next lower available
 *	 rate, until reaching the lowest available rate.
 *    c) When reducing rate, also switch antenna selection.
 *    b) Once lowest available rate is reached, repreat this rate until
 *   rate table is filled(16 entries),switching antenna each entry.
