  41  Initial driver on which this is based was developed by Janusz Gorycki,
  42  Maciej Urbaniak, and Maciej Sosnowski.
  43
  44  Promiscuous mode support added by Jacek Wysoczynski and Maciej Urbaniak.
  45
  46 Theory of Operation
  47
  48 Tx - Commands and Data
  49
  50 Firmware and host share a circular queue of Transmit Buffer Descriptors (TBDs)
  51 Each TBD contains a pointer to the physical (dma_addr_t) address of data being
  52 sent to the firmware as well as the length of the data.
  53
  54 The host writes to the TBD queue at the WRITE index.  The WRITE index points
  55 to the _next_ packet to be written and is advanced when after the TBD has been
  56 filled.
  57
  58 The firmware pulls from the TBD queue at the READ index.  The READ index points
  59 to the currently being read entry, and is advanced once the firmware is
  60 done with a packet.
  61
  62 When data is sent to the firmware, the first TBD is used to indicate to the
  63 firmware if a Command or Data is being sent.  If it is Command, all of the
  64 command information is contained within the physical address referred to by the
  65 TBD.  If it is Data, the first TBD indicates the type of data packet, number
  66 of fragments, etc.  The next TBD then refers to the actual packet location.
  67
  68 The Tx flow cycle is as follows:
  69
  70 1) ipw2100_tx() is called by kernel with SKB to transmit
  71 2) Packet is move from the tx_free_list and appended to the transmit pending
  72    list (tx_pend_list)
  73 3) work is scheduled to move pending packets into the shared circular queue.
  74 4) when placing packet in the circular queue, the incoming SKB is DMA mapped
  75    to a physical address.  That address is entered into a TBD.  Two TBDs are
  76    filled out.  The first indicating a data packet, the second referring to the
  77    actual payload data.
  78 5) the packet is removed from tx_pend_list and placed on the end of the
  79    firmware pending list (fw_pend_list)
  80 6) firmware is notified that the WRITE index has
  81 7) Once the firmware has processed the TBD, INTA is triggered.
  82 8) For each Tx interrupt received from the firmware, the READ index is checked
  83    to see which TBDs are done being processed.
  84 9) For each TBD that has been processed, the ISR pulls the oldest packet
  85    from the fw_pend_list.
  86 10)The packet structure contained in the fw_pend_list is then used
  87    to unmap the DMA address and to free the SKB originally passed to the driver
  88    from the kernel.
  89 11)The packet structure is placed onto the tx_free_list
  90
  91 The above steps are the same for commands, only the msg_free_list/msg_pend_list
  92 are used instead of tx_free_list/tx_pend_list
  93
  94 ...
  95
  96 Critical Sections / Locking :
  97
  98 There are two locks utilized.  The first is the low level lock (priv->low_lock)
  99 that protects the following:
 100
 101 - Access to the Tx/Rx queue lists via priv->low_lock. The lists are as follows:
 102
 103   tx_free_list : Holds pre-allocated Tx buffers.
 104     TAIL modified in __ipw2100_tx_process()
 105     HEAD modified in ipw2100_tx()
 106
 107   tx_pend_list : Holds used Tx buffers waiting to go into the TBD ring
 108     TAIL modified ipw2100_tx()
 109     HEAD modified by ipw2100_tx_send_data()
 110
 111   msg_free_list : Holds pre-allocated Msg (Command) buffers
 112     TAIL modified in __ipw2100_tx_process()
 113     HEAD modified in ipw2100_hw_send_command()
 114
 115   msg_pend_list : Holds used Msg buffers waiting to go into the TBD ring
 116     TAIL modified in ipw2100_hw_send_command()
 117     HEAD modified in ipw2100_tx_send_commands()
 118
 119   The flow of data on the TX side is as follows:
 120
 121   MSG_FREE_LIST + COMMAND => MSG_PEND_LIST => TBD => MSG_FREE_LIST
 122   TX_FREE_LIST + DATA => TX_PEND_LIST => TBD => TX_FREE_LIST
 123
 124   The methods that work on the TBD ring are protected via priv->low_lock.
 125
 126 - The internal data state of the device itself
 127 - Access to the firmware read/write indexes for the BD queues
 128   and associated logic
 129
 130 All external entry functions are locked with the priv->action_lock to ensure
 131 that only one external action is invoked at a time.

2822  * Read index - points to the next TBD that the firmware will
2823  *              process.  The firmware will read the data, and once
2824  *              done processing, it will advance the Read index.
2825  *
2826  * Write index - driver fills this entry with an constructed TBD
2827  *               entry.  The Write index is not advanced until the
2828  *               packet has been configured.

2830  * In between the W and R indexes are the TBDs that have NOT been
2831  * processed.  Lagging behind the R index are packets that have
2832  * been processed but have not been freed by the driver.
2833  *
2834  * In order to free old storage, an internal index will be maintained
2835  * that points to the next packet to be freed.  When all used
2836  * packets have been freed, the oldest index will be the same as the
2837  * firmware's read index.
2838  *
2839  * The OLDEST index is cached in the variable 'priv->tx_queue.oldest'
