+ * like http://www.autosar.org/download/R4.0/AUTOSAR_SWS_E2ELibrary.pdf
+ * E.g. the profile_data[] may contain additional u8 values (called DATA_IDs)
+ * that are used depending on counter values inside the CAN frame data[].
+ * So far only three profiles have been implemented for illustration.

+/*
+ * There are several things to be aware of that aren't at all obvious:
+ *
+ *
+ * SOCKETS, SOCKET SETS, BANKS, ROWS, CHIP-SELECT ROWS, CHANNELS, etc..
+ *
+ * These are some of the many terms that are thrown about that don't always
+ * mean what people think they mean (Inconceivable!).  In the interest of
+ * creating a common ground for discussion, terms and their definitions
+ * will be established.
+ *
+ * Memory devices:      The individual chip on a memory stick.  These devices
+ *                      commonly output 4 and 8 bits each.  Grouping several
+ *                      of these in parallel provides 64 bits which is common
+ *                      for a memory stick.
+ *
+ * Memory Stick:        A printed circuit board that aggregates multiple
+ *                      memory devices in parallel.  This is the atomic
+ *                      memory component that is purchaseable by Joe consumer
+ *                      and loaded into a memory socket.
+ *
+ * Socket:              A physical connector on the motherboard that accepts
+ *                      a single memory stick.
+ *
+ * Channel:             Set of memory devices on a memory stick that must be
+ *                      grouped in parallel with one or more additional
+ *                      channels from other memory sticks.  This parallel
+ *                      grouping of the output from multiple channels are
+ *                      necessary for the smallest granularity of memory access.
+ *                      Some memory controllers are capable of single channel -
+ *                      which means that memory sticks can be loaded
+ *                      individually.  Other memory controllers are only
+ *                      capable of dual channel - which means that memory
+ *                      sticks must be loaded as pairs (see "socket set").
+ *
+ * Chip-select row:     All of the memory devices that are selected together.
+ *                      for a single, minimum grain of memory access.
+ *                      This selects all of the parallel memory devices across
+ *                      all of the parallel channels.  Common chip-select rows
+ *                      for single channel are 64 bits, for dual channel 128
+ *                      bits.
+ *
+ * Single-Ranked stick: A Single-ranked stick has 1 chip-select row of memory.
+ *                      Motherboards commonly drive two chip-select pins to
+ *                      a memory stick. A single-ranked stick, will occupy
+ *                      only one of those rows. The other will be unused.
+ *
+ * Double-Ranked stick: A double-ranked stick has two chip-select rows which
+ *                      access different sets of memory devices.  The two
+ *                      rows cannot be accessed concurrently.
+ *
+ * Double-sided stick:  DEPRECATED TERM, see Double-Ranked stick.
+ *                      A double-sided stick has two chip-select rows which
+ *                      access different sets of memory devices.  The two
+ *                      rows cannot be accessed concurrently.  "Double-sided"
+ *                      is irrespective of the memory devices being mounted
+ *                      on both sides of the memory stick.
+ *
+ * Socket set:          All of the memory sticks that are required for
+ *                      a single memory access or all of the memory sticks
+ *                      spanned by a chip-select row.  A single socket set
+ *                      has two chip-select rows and if double-sided sticks
+ *                      are used these will occupy those chip-select rows.
+ *
+ * Bank:                This term is avoided because it is unclear when
+ *                      needing to distinguish between chip-select rows and
+ *                      socket sets.
+ *

+ * Virtual pages:

 /**
+ * DOC: AP support for powersaving clients
+ *
+ * In order to implement AP and P2P GO modes, mac80211 has support for
+ * client powersaving, both "legacy" PS (PS-Poll/null data) and uAPSD.
+ * There currently is no support for sAPSD.
+ *
+ * There is one assumption that mac80211 makes, namely that a client
+ * will not poll with PS-Poll and trigger with uAPSD at the same time.
+ * Both are supported, and both can be used by the same client, but
+ * they can't be used concurrently by the same client. This simplifies
+ * the driver code.
+ *
+ * The first thing to keep in mind is that there is a flag for complete
+ * driver implementation: %IEEE80211_HW_AP_LINK_PS. If this flag is set,
+ * mac80211 expects the driver to handle most of the state machine for
+ * powersaving clients and will ignore the PM bit in incoming frames.
+ * Drivers then use ieee80211_sta_ps_transition() to inform mac80211 of
+ * stations' powersave transitions. In this mode, mac80211 also doesn't
+ * handle PS-Poll/uAPSD.
+ *
+ * In the mode without %IEEE80211_HW_AP_LINK_PS, mac80211 will check the
+ * PM bit in incoming frames for client powersave transitions. When a
+ * station goes to sleep, we will stop transmitting to it. There is,
+ * however, a race condition: a station might go to sleep while there is
+ * data buffered on hardware queues. If the device has support for this
+ * it will reject frames, and the driver should give the frames back to
+ * mac80211 with the %IEEE80211_TX_STAT_TX_FILTERED flag set which will
+ * cause mac80211 to retry the frame when the station wakes up. The
+ * driver is also notified of powersave transitions by calling its
+ * @sta_notify callback.
+ *
+ * When the station is asleep, it has three choices: it can wake up,
+ * it can PS-Poll, or it can possibly start a uAPSD service period.
+ * Waking up is implemented by simply transmitting all buffered (and
+ * filtered) frames to the station. This is the easiest case. When
+ * the station sends a PS-Poll or a uAPSD trigger frame, mac80211
+ * will inform the driver of this with the @allow_buffered_frames
+ * callback; this callback is optional. mac80211 will then transmit
+ * the frames as usual and set the %IEEE80211_TX_CTL_POLL_RESPONSE
+ * on each frame. The last frame in the service period (or the only
+ * response to a PS-Poll) also has %IEEE80211_TX_STATUS_EOSP set to
+ * indicate that it ends the service period; as this frame must have
+ * TX status report it also sets %IEEE80211_TX_CTL_REQ_TX_STATUS.
+ * When TX status is reported for this frame, the service period is
+ * marked has having ended and a new one can be started by the peer.
+ *
+ * Another race condition can happen on some devices like iwlwifi
+ * when there are frames queued for the station and it wakes up
+ * or polls; the frames that are already queued could end up being
+ * transmitted first instead, causing reordering and/or wrong
+ * processing of the EOSP. The cause is that allowing frames to be
+ * transmitted to a certain station is out-of-band communication to
+ * the device. To allow this problem to be solved, the driver can
+ * call ieee80211_sta_block_awake() if frames are buffered when it
+ * is notified that the station went to sleep. When all these frames
+ * have been filtered (see above), it must call the function again
+ * to indicate that the station is no longer blocked.
+ *
+ * If the driver buffers frames in the driver for aggregation in any
+ * way, it must use the ieee80211_sta_set_buffered() call when it is
+ * notified of the station going to sleep to inform mac80211 of any
+ * TIDs that have frames buffered. Note that when a station wakes up
+ * this information is reset (hence the requirement to call it when
+ * informed of the station going to sleep). Then, when a service
+ * period starts for any reason, @release_buffered_frames is called
+ * with the number of frames to be released and which TIDs they are
+ * to come from. In this case, the driver is responsible for setting
+ * the EOSP (for uAPSD) and MORE_DATA bits in the released frames,
+ * to help the @more_data paramter is passed to tell the driver if
+ * there is more data on other TIDs -- the TIDs to release frames
+ * from are ignored since mac80211 doesn't know how many frames the
+ * buffers for those TIDs contain.
+ *
+ * If the driver also implement GO mode, where absence periods may
+ * shorten service periods (or abort PS-Poll responses), it must
+ * filter those response frames except in the case of frames that
+ * are buffered in the driver -- those must remain buffered to avoid
+ * reordering. Because it is possible that no frames are released
+ * in this case, the driver must call ieee80211_sta_eosp_irqsafe()
+ * to indicate to mac80211 that the service period ended anyway.
+ *
+ * Finally, if frames from multiple TIDs are released from mac80211
+ * but the driver might reorder them, it must clear & set the flags
+ * appropriately (only the last frame may have %IEEE80211_TX_STATUS_EOSP)
+ * and also take care of the EOSP and MORE_DATA bits in the frame.
+ * The driver may also use ieee80211_sta_eosp_irqsafe() in this case.

+ *      if there are more frames on the given TIDs, and if there are more than
+ *      the frames being released then it must still set the more-data bit in
+ *      the frame. If the @more_data parameter is %true, then of course the
+ *      more-data bit must always be set.
+ *      The @tids parameter tells the driver which TIDs to release frames
+ *      from, for PS-poll it will always have only a single bit set.
+ *      In the case this is used for a PS-poll initiated release, the
+ *      @num_frames parameter will always be 1 so code can be shared. In
+ *      this case the driver must also set %IEEE80211_TX_STATUS_EOSP flag
+ *      on the TX status (and must report TX status) so that the PS-poll
+ *      period is properly ended. This is used to avoid sending multiple
+ *      responses for a retried PS-poll frame.
+ *      In the case this is used for uAPSD, the @num_frames parameter may be
+ *      bigger than one, but the driver may send fewer frames (it must send
+ *      at least one, however). In this case it is also responsible for
+ *      setting the EOSP flag in the QoS header of the frames. Also, when the
+ *      service period ends, the driver must set %IEEE80211_TX_STATUS_EOSP
+ *      on the last frame in the SP. Alternatively, it may call the function
+ *      ieee80211_sta_eosp_irqsafe() to inform mac80211 of the end of the SP.
+ *      This callback must be atomic.
+ * @allow_buffered_frames: Prepare device to allow the given number of frames
+ *      to go out to the given station. The frames will be sent by mac80211
+ *      via the usual TX path after this call. The TX information for frames
+ *      released will also have the %IEEE80211_TX_CTL_POLL_RESPONSE flag set
+ *      and the last one will also have %IEEE80211_TX_STATUS_EOSP set. In case
+ *      frames from multiple TIDs are released and the driver might reorder
+ *      them between the TIDs, it must set the %IEEE80211_TX_STATUS_EOSP flag
+ *      on the last frame and clear it on all others and also handle the EOSP
+ *      bit in the QoS header correctly. Alternatively, it can also call the
+ *      ieee80211_sta_eosp_irqsafe() function.
+ *      The @tids parameter is a bitmap and tells the driver which TIDs the
+ *      frames will be on; it will at most have two bits set.
+ *      This callback must be atomic.
