What: b43 support for firmware revision < 410
-When: July 2008
+When: The schedule was July 2008, but it was decided that we are going to keep the
+ code as long as there are no major maintanance headaches.
+ So it _could_ be removed _any_ time now, if it conflicts with something new.
Why: The support code for the old firmware hurts code readability/maintainability
and slightly hurts runtime performance. Bugfixes for the old firmware
are not provided by Broadcom anymore.

- * REPLY_SCAN_CMD = 0x80 (command)
- *
- * The hardware scan command is very powerful; the driver can set it up to
- * maintain (relatively) normal network traffic while doing a scan in the
- * background. The max_out_time and suspend_time control the ratio of how
- * long the device stays on an associated network channel ("service channel")
- * vs. how long it's away from the service channel, tuned to other channels
- * for scanning.
- *
- * max_out_time is the max time off-channel (in usec), and suspend_time
- * is how long (in "extended beacon" format) that the scan is "suspended"
- * after returning to the service channel. That is, suspend_time is the
- * time that we stay on the service channel, doing normal work, between
- * scan segments. The driver may set these parameters differently to support
- * scanning when associated vs. not associated, and light vs. heavy traffic
- * loads when associated.
- *
- * After receiving this command, the device's scan engine does the following;
- *
- * 1) Sends SCAN_START notification to driver
- * 2) Checks to see if it has time to do scan for one channel
- * 3) Sends NULL packet, with power-save (PS) bit set to 1,
- * to tell AP that we're going off-channel
- * 4) Tunes to first channel in scan list, does active or passive scan
- * 5) Sends SCAN_RESULT notification to driver
- * 6) Checks to see if it has time to do scan on *next* channel in list
- * 7) Repeats 4-6 until it no longer has time to scan the next channel
- * before max_out_time expires
- * 8) Returns to service channel
- * 9) Sends NULL packet with PS=0 to tell AP that we're back
- * 10) Stays on service channel until suspend_time expires
- * 11) Repeats entire process 2-10 until list is complete
- * 12) Sends SCAN_COMPLETE notification
- *
- * For fast, efficient scans, the scan command also has support for staying on
- * a channel for just a short time, if doing active scanning and getting no
- * responses to the transmitted probe request. This time is controlled by
- * quiet_time, and the number of received packets below which a channel is
- * considered "quiet" is controlled by quiet_plcp_threshold.
- *
- * For active scanning on channels that have regulatory restrictions against
- * blindly transmitting, the scan can listen before transmitting, to make sure
- * that there is already legitimate activity on the channel. If enough
- * packets are cleanly received on the channel (controlled by good_CRC_th,
- * typical value 1), the scan engine starts transmitting probe requests.
- *
- * Driver must use separate scan commands for 2.4 vs. 5 GHz bands.
- *
- * To avoid uCode errors, see timing restrictions described under
- * struct iwl3945_scan_channel.

+ * notifies host via "initialize alive" that it is complete.
+ *
+ * The host then replaces the BSM_DRAM_* pointer values to point to the
+ * normal runtime uCode instructions and a backup uCode data cache buffer
+ * (filled initially with starting data values for the on-board processor),
+ * then triggers the "initialize" uCode to load and launch the runtime uCode,
+ * which begins normal operation.
+ *
+ * When doing a power-save shutdown, runtime uCode saves data SRAM into
+ * the backup data cache in DRAM before SRAM is powered down.

-/*************** DMA-QUEUE-GENERAL-FUNCTIONS *****
- * DMA services
- *
- * Theory of operation
- *
- * A Tx or Rx queue resides in host DRAM, and is comprised of a circular buffer
- * of buffer descriptors, each of which points to one or more data buffers for
- * the device to read from or fill. Driver and device exchange status of each
- * queue via "read" and "write" pointers. Driver keeps minimum of 2 empty
- * entries in each circular buffer, to protect against confusing empty and full
- * queue states.
- *
- * The device reads or writes the data in the queues via the device's several
- * DMA/FIFO channels. Each queue is mapped to a single DMA channel.
- *
- * 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 3945 operates with six queues: One receive queue, one transmit queue
- * (#4) for sending commands to the device firmware, and four transmit queues
- * (#0-3) for data tx via EDCA. An additional 2 HCCA queues are unused.

- *
- * For example, iwl3945_priv->eeprom.band_3_channels[4] from the band_3

- * During init, we copy the eeprom information and channel map
- * information into priv->channel_info_24/52 and priv->channel_map_24/52
- *
- * channel_map_24/52 provides the index in the channel_info array for a
- * given channel. We have to have two separate maps as there is channel
- * overlap with the 2.4GHz and 5.2GHz spectrum as seen in band_1 and
- * band_2
- *
- * A value of 0xff stored in the channel_map indicates that the channel
- * is not supported by the hardware at all.
- *
- * A value of 0xfe in the channel_map indicates that the channel is not
- * valid for Tx with the current hardware. This means that
- * while the system can tune and receive on a given channel, it may not
- * be able to associate or transmit any frames on that

- * iwl3945_load_bsm - Load bootstrap instructions
- *
- * BSM operation:
- *
- * The Bootstrap State Machine (BSM) stores a short bootstrap uCode program
- * in special SRAM that does not power down during RFKILL. When powering back
- * up after power-saving sleeps (or during initial uCode load), the BSM loads
- * the bootstrap program into the on-board processor, and starts it.
- *
- * The bootstrap program loads (via DMA) instructions and data for a new
- * program from host DRAM locations indicated by the host driver in the
- * BSM_DRAM_* registers. Once the new program is loaded, it starts
- * automatically.
- *
- * When initializing the NIC, the host driver points the BSM to the
- * "initialize" uCode image. This uCode sets up some internal data, then
- * notifies host via "initialize alive" that it is complete.
- *
- * The host then replaces the BSM_DRAM_* pointer values to point to the
- * normal runtime uCode instructions and a backup uCode data cache buffer
- * (filled initially with starting data values for the on-board processor),
- * then triggers the "initialize" uCode to load and launch the runtime uCode,
- * which begins normal operation.
- *
- * When doing a power-save shutdown, runtime uCode saves data SRAM into
- * the backup data cache in DRAM before SRAM is powered down.
- *
- * When powering back up, the BSM loads the bootstrap program. This reloads
- * the runtime uCode instructions and the backup data cache into SRAM,
- * and re-launches the runtime uCode from where it left off.

+ ---help---
+ A driver for 802.11b wireless cards based on the "Hermes" or
+ Intersil HFA384x (Prism 2) MAC controller. This includes the vast
+ majority of the PCMCIA 802.11b cards (which are nearly all rebadges)
+ - except for the Cisco/Aironet cards. Cards supported include the
+ Apple Airport (not a PCMCIA card), WavelanIEEE/Orinoco,
+ Cabletron/EnteraSys Roamabout, ELSA AirLancer, MELCO Buffalo, Avaya,
+ IBM High Rate Wireless, Farralon Syyline, Samsung MagicLAN, Netgear
+ MA401, LinkSys WPC-11, D-Link DWL-650, 3Com AirConnect, Intel
+ IPW2011, and Symbol Spectrum24 High Rate amongst others.
+
+ This option includes the guts of the driver, but in order to
+ actually use a card you will also need to enable support for PCMCIA
+ Hermes cards, PLX9052 based PCI adaptors or the Apple Airport below.
+
+ You will also very likely also need the Wireless Tools in order to
+ configure your card and that /etc/pcmcia/wireless.opts works :

+ * itself, such hardware should simply set the %IEEE80211_HW_SUPPORTS_PS
+ * hardware flag. In that case, it will be told about the desired
+ * powersave mode depending on the association status, and the driver
+ * must take care of sending nullfunc frames when necessary, i.e. when
+ * entering and leaving powersave mode. The driver is required to look at
+ * the AID in beacons and signal to the AP that it woke up when it finds
+ * traffic directed to it. This mode supports dynamic PS by simply
+ * enabling/disabling PS.
+ *
+ * Additionally, such hardware may set the %IEEE80211_HW_SUPPORTS_DYNAMIC_PS
+ * flag to indicate that it can support dynamic PS mode itself (see below).
+ *
+ * Other hardware designs cannot send nullfunc frames by themselves and also
+ * need software support for parsing the TIM bitmap. This is also supported
+ * by mac80211 by combining the %IEEE80211_HW_SUPPORTS_PS and
+ * %IEEE80211_HW_PS_NULLFUNC_STACK flags. The hardware is of course still
+ * required to pass up beacons. Additionally, in this case, mac80211 will
+ * wake up the hardware when multicast traffic is announced in the beacon.
+ *
+ * FIXME: I don't think we can be fast enough in software when we want to
+ * receive multicast traffic?
+ *
+ * Dynamic powersave mode is an extension to normal powersave mode in which
+ * the hardware stays awake for a user-specified period of time after sending
+ * a frame so that reply frames need not be buffered and therefore delayed
+ * to the next wakeup. This can either be supported by hardware, in which case
+ * the driver needs to look at the @dynamic_ps_timeout hardware configuration
