+        Shared driver code for IEEE 802.11b wireless cards based on
+        Intersil Prism2/2.5/3 chipset. This driver supports so called
+        Host AP mode that allows the card to act as an IEEE 802.11
+        access point.
+
+        See <http://hostap.epitest.fi/> for more information about the
+        Host AP driver configuration and tools. This site includes
+        information and tools (hostapd and wpa_supplicant) for WPA/WPA2
+        support.
+
+        This option includes the base Host AP driver code that is shared by
+        different hardware models. You will also need to enable support for
+        PLX/PCI/CS version of the driver to actually use the driver.
+
+        The driver can be compiled as a module and it will be called

+ *
+ * FIX:
+ * - there is currently no way of associating TX packets to correct wds device
+ *   when TX Exc/OK event occurs, so all tx_packets and some
+ *   tx_errors/tx_dropped are added to the main netdevice; using sw_support
+ *   field in txdesc might be used to fix this (using Alloc event to increment
+ *   tx_packets would need some further info in txfid table)
+ *
+ * Buffer Access Path (BAP) usage:
+ *   Prism2 cards have two separate BAPs for accessing the card memory. These
+ *   should allow concurrent access to two different frames and the driver
+ *   previously used BAP0 for sending data and BAP1 for receiving data.
+ *   However, there seems to be number of issues with concurrent access and at
+ *   least one know hardware bug in using BAP0 and BAP1 concurrently with PCI
+ *   Prism2.5. Therefore, the driver now only uses BAP0 for moving data between
+ *   host and card memories. BAP0 accesses are protected with local->baplock
+ *   (spin_lock_bh) to prevent concurrent use.

+
+ 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 referrs 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.

+ * 2 empty entries always kept in the buffer to protect from overflow.
+ *
+ * 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 CX2_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
