+
+ Initial driver on which this is based was developed by Janusz Gorycki,
+ Maciej Urbaniak, and Maciej Sosnowski.
+
+ Promiscuous mode support added by Jacek Wysoczynski and Maciej Urbaniak.
+
+Theory of Operation
+
+Tx - Commands and Data
+
+Firmware and host share a circular queue of Transmit Buffer Descriptors (TBDs)
+Each TBD contains a pointer to the physical (dma_addr_t) address of data being
+sent to the firmware as well as the length of the data.
+
+The host writes to the TBD queue at the WRITE index. The WRITE index points
+to the _next_ packet to be written and is advanced when after the TBD has been
+filled.
+
+The firmware pulls from the TBD queue at the READ index. The READ index points
+to the currently being read entry, and is advanced once the firmware is
+done with a packet.
+
+When data is sent to the firmware, the first TBD is used to indicate to the
+firmware if a Command or Data is being sent. If it is Command, all of the
+command information is contained within the physical address referred to by the
+TBD. If it is Data, the first TBD indicates the type of data packet, number
+of fragments, etc. The next TBD then refers to the actual packet location.
+
+The Tx flow cycle is as follows:
+
+1) ipw2100_tx() is called by kernel with SKB to transmit
+2) Packet is move from the tx_free_list and appended to the transmit pending
+ list (tx_pend_list)
+3) work is scheduled to move pending packets into the shared circular queue.
+4) when placing packet in the circular queue, the incoming SKB is DMA mapped
+ to a physical address. That address is entered into a TBD. Two TBDs are
+ filled out. The first indicating a data packet, the second referring to the
+ actual payload data.
+5) the packet is removed from tx_pend_list and placed on the end of the
+ firmware pending list (fw_pend_list)
+6) firmware is notified that the WRITE index has
+7) Once the firmware has processed the TBD, INTA is triggered.
+8) For each Tx interrupt received from the firmware, the READ index is checked
+ to see which TBDs are done being processed.
+9) For each TBD that has been processed, the ISR pulls the oldest packet
+ from the fw_pend_list.
+10)The packet structure contained in the fw_pend_list is then used
+ to unmap the DMA address and to free the SKB originally passed to the driver
+ from the kernel.
+11)The packet structure is placed onto the tx_free_list
+
+The above steps are the same for commands, only the msg_free_list/msg_pend_list
+are used instead of tx_free_list/tx_pend_list
+
+...
+
+Critical Sections / Locking :
+
+There are two locks utilized. The first is the low level lock (priv->low_lock)
+that protects the following:
+
+- Access to the Tx/Rx queue lists via priv->low_lock. The lists are as follows:
+
+ tx_free_list : Holds pre-allocated Tx buffers.
+ TAIL modified in __ipw2100_tx_process()
+ HEAD modified in ipw2100_tx()
+
+ tx_pend_list : Holds used Tx buffers waiting to go into the TBD ring
+ TAIL modified ipw2100_tx()
+ HEAD modified by ipw2100_tx_send_data()
+
+ msg_free_list : Holds pre-allocated Msg (Command) buffers
+ TAIL modified in __ipw2100_tx_process()
+ HEAD modified in ipw2100_hw_send_command()
+
+ msg_pend_list : Holds used Msg buffers waiting to go into the TBD ring
+ TAIL modified in ipw2100_hw_send_command()
+ HEAD modified in ipw2100_tx_send_commands()
+
+ The flow of data on the TX side is as follows:
+
+ MSG_FREE_LIST + COMMAND => MSG_PEND_LIST => TBD => MSG_FREE_LIST
+ TX_FREE_LIST + DATA => TX_PEND_LIST => TBD => TX_FREE_LIST
+
+ The methods that work on the TBD ring are protected via priv->low_lock.
+
+- The internal data state of the device itself
+- Access to the firmware read/write indexes for the BD queues
+ and associated logic
+
+All external entry functions are locked with the priv->action_lock to ensure
+that only one external action is invoked at a time.

+ *
+ * For Tx queue, there are low mark and high mark limits. If, after queuing
+ * the packet for Tx, free space become < low mark, Tx queue stopped. When
+ * reclaiming packets (on 'tx done IRQ), if free space become > high mark,
+ * Tx queue resumed.
+ *
+ * The IPW operates with six queues, one receive queue in the device's
+ * sram, one transmit queue for sending commands to the device firmware,
+ * and four transmit queues for data.
+ *
+ * The four transmit queues allow for performing quality of service (qos)
+ * transmissions as per the 802.11 protocol. Currently Linux does not
+ * provide a mechanism to the user for utilizing prioritized queues, so
+ * we only utilize the first data transmit queue (queue1).

+ * Rx theory of operation
+ *
+ * The host allocates 32 DMA target addresses and passes the host address
+ * to the firmware at register IPW_RFDS_TABLE_LOWER + N * RFD_SIZE where N is
+ * 0 to 31
+ *
+ * Rx Queue Indexes
+ * The host/firmware share two index registers for managing the Rx buffers.
+ *
+ * The READ index maps to the first position that the firmware may be writing
+ * to -- the driver can read up to (but not including) this position and get
+ * good data.
+ * The READ index is managed by the firmware once the card is enabled.
+ *
+ * The WRITE index maps to the last position the driver has read from -- the
+ * position preceding WRITE is the last slot the firmware can place a packet.
+ *
+ * The queue is empty (no good data) if WRITE = READ - 1, and is full if
+ * WRITE = READ.
+ *
+ * During initialization the host sets up the READ queue position to the first
+ * INDEX position, and WRITE to the last (READ - 1 wrapped)
+ *
+ * When the firmware places a packet in a buffer it will advance the READ index
+ * and fire the RX interrupt. The driver can then query the READ index and
+ * process as many packets as possible, moving the WRITE index forward as it
+ * resets the Rx queue buffers with new memory.
+ *
+ * The management in the driver is as follows:
+ * + A list of pre-allocated SKBs is stored in ipw->rxq->rx_free. When
+ * ipw->rxq->free_count drops to or below RX_LOW_WATERMARK, work is scheduled
+ * to replensish the ipw->rxq->rx_free.
+ * + In ipw_rx_queue_replenish (scheduled) if 'processed' != 'read' then the
+ * ipw->rxq is replenished and the READ INDEX is updated (updating the
+ * 'processed' and 'read' driver indexes as well)
+ * + A received packet is processed and handed to the kernel network stack,
+ * detached from the ipw->rxq. The driver 'processed' index is updated.
+ * + The Host/Firmware ipw->rxq is replenished at tasklet time from the rx_free
+ * list. If there are no allocated buffers in ipw->rxq->rx_free, the READ
+ * INDEX is not incremented and ipw->status(RX_STALLED) is set. If there
+ * were enough free buffers and RX_STALLED is set it is cleared.
+ *
+ *
+ * Driver sequence:
+ *
+ * ipw_rx_queue_alloc() Allocates rx_free
+ * ipw_rx_queue_replenish() Replenishes rx_free list from rx_used, and calls
+ * ipw_rx_queue_restock
+ * ipw_rx_queue_restock() Moves available buffers from rx_free into Rx
+ * queue, updates firmware pointers, and updates
+ * the WRITE index. If insufficient rx_free buffers
+ * are available, schedules ipw_rx_queue_replenish
+ *
+ * -- enable interrupts --
+ * ISR - ipw_rx() Detach ipw_rx_mem_buffers from pool up to the
+ * READ INDEX, detaching the SKB from the pool.
+ * Moves the packet buffer from queue to rx_used.
+ * Calls ipw_rx_queue_restock to refill any empty
+ * slots.
+ * ...

+
+In the event that fragmentation is required, the incoming payload is split into
+N parts of size ieee->fts. The first fragment contains the SNAP header and the
+remaining packets are just data.
+
+If encryption is enabled, each fragment payload size is reduced by enough space
+to add the prefix and postfix (IV and ICV totalling 8 bytes in the case of WEP)
+So if you have 1500 bytes of payload with ieee->fts set to 500 without
+encryption it will take 3 frames. With WEP it will take 4 frames as the
+payload of each frame is reduced to 492 bytes.
