+ * are introduced: 3, 2, 1, 0.5 and 0.25 MBit/s.
+ *
+ * Please note that can you either use XR or TURBO but you cannot use both,

+ * Modulation for Atheros' Turbo G and Turbo A, its supposed to provide a
+ * throughput transmission speed up to 40Mbit/s-60Mbit/s at a 108Mbit/s
+ * signaling rate achieved through the bonding of two 54Mbit/s 802.11g
+ * channels. To use this feature your Access Point must also suport it.
+ * There is also a distinction between "static" and "dynamic" turbo modes:
+ *
+ * - Static: is the dumb version: devices set to this mode stick to it until
+ *     the mode is turned off.
+ * - Dynamic: is the intelligent version, the network decides itself if it
+ *     is ok to use turbo. As soon as traffic is detected on adjacent channels
+ *     (which would get used in turbo mode), or when a non-turbo station joins
+ *     the network, turbo mode won't be used until the situation changes again.
+ *     Dynamic mode is achieved by Atheros' Adaptive Radio (AR) feature which
+ *     monitors the used radio band in order to decide whether turbo mode may
+ *     be used or not.
+ *
+ * This article claims Super G sticks to bonding of channels 5 and 6 for
+ * USA:
+ *
+ * http://www.pcworld.com/article/id,113428-page,1/article.html
+ *
+ * The channel bonding seems to be driver specific though. In addition to
+ * deciding what channels will be used, these "Turbo" modes are accomplished
+ * by also enabling the following features:
+ *
+ * - Bursting: allows multiple frames to be sent at once, rather than pausing
+ *     after each frame. Bursting is a standards-compliant feature that can be
+ *     used with any Access Point.
+ * - Fast frames: increases the amount of information that can be sent per
+ *     frame, also resulting in a reduction of transmission overhead. It is a
+ *     proprietary feature that needs to be supported by the Access Point.
+ * - Compression: data frames are compressed in real time using a Lempel Ziv
+ *     algorithm. This is done transparently. Once this feature is enabled,
+ *     compression and decompression takes place inside the chipset, without
+ *     putting additional load on the host CPU.

+/**
+ * ath5k_hw_set_bssid_mask - set common bits we should listen to
+ *
+ * The bssid_mask is a utility used by AR5212 hardware to inform the hardware
+ * which bits of the interface's MAC address should be looked at when trying
+ * to decide which packets to ACK. In station mode every bit matters. In AP
+ * mode with a single BSS every bit matters as well. In AP mode with
+ * multiple BSSes not every bit matters.
+ *
+ * @ah: the &struct ath5k_hw
+ * @mask: the bssid_mask, a u8 array of size ETH_ALEN
+ *
+ * Note that this is a simple filter and *does* not filter out all
+ * relevant frames. Some non-relevant frames will get through, probability
+ * jocks are welcomed to compute.
+ *
+ * When handling multiple BSSes (or VAPs) you can get the BSSID mask by
+ * computing the set of:
+ *
+ *     ~ ( MAC XOR BSSID )
+ *
+ * When you do this you are essentially computing the common bits. Later it
+ * is assumed the harware will "and" (&) the BSSID mask with the MAC address
+ * to obtain the relevant bits which should match on the destination frame.
+ *
+ * Simple example: on your card you have have two BSSes you have created with
+ * BSSID-01 and BSSID-02. Lets assume BSSID-01 will not use the MAC address.
+ * There is another BSSID-03 but you are not part of it. For simplicity's sake,
+ * assuming only 4 bits for a mac address and for BSSIDs you can then have:
+ *
+ *                  \
+ * MAC:                0001 |
+ * BSSID-01:   0100 | --> Belongs to us
+ * BSSID-02:   1001 |
+ *                  /
+ * -------------------
+ * BSSID-03:   0110  | --> External
+ * -------------------
+ *
+ * Our bssid_mask would then be:
+ *
+ *             On loop iteration for BSSID-01:
+ *             ~(0001 ^ 0100)  -> ~(0101)
+ *                             ->   1010
+ *             bssid_mask      =    1010
+ *
+ *             On loop iteration for BSSID-02:
+ *             bssid_mask &= ~(0001   ^   1001)
+ *             bssid_mask =   (1010)  & ~(0001 ^ 1001)
+ *             bssid_mask =   (1010)  & ~(1001)
+ *             bssid_mask =   (1010)  &  (0110)
+ *             bssid_mask =   0010
+ *
+ * A bssid_mask of 0010 means "only pay attention to the second least
+ * significant bit". This is because its the only bit common
+ * amongst the MAC and all BSSIDs we support. To findout what the real
+ * common bit is we can simply "&" the bssid_mask now with any BSSID we have
+ * or our MAC address (we assume the hardware uses the MAC address).
+ *
+ * Now, suppose there's an incoming frame for BSSID-03:
+ *
+ * IFRAME-01:  0110
+ *
+ * An easy eye-inspeciton of this already should tell you that this frame
+ * will not pass our check. This is beacuse the bssid_mask tells the
+ * hardware to only look at the second least significant bit and the
+ * common bit amongst the MAC and BSSIDs is 0, this frame has the 2nd LSB
+ * as 1, which does not match 0.
+ *
+ * So with IFRAME-01 we *assume* the hardware will do:
+ *
+ *     allow = (IFRAME-01 & bssid_mask) == (bssid_mask & MAC) ? 1 : 0;
+ *  --> allow = (0110 & 0010) == (0010 & 0001) ? 1 : 0;
+ *  --> allow = (0010) == 0000 ? 1 : 0;
+ *  --> allow = 0
+ *
+ *  Lets now test a frame that should work:
+ *
+ * IFRAME-02:  0001 (we should allow)
+ *
+ *     allow = (0001 & 1010) == 1010
+ *
+ *     allow = (IFRAME-02 & bssid_mask) == (bssid_mask & MAC) ? 1 : 0;
+ *  --> allow = (0001 & 0010) ==  (0010 & 0001) ? 1 :0;
+ *  --> allow = (0010) == (0010)
+ *  --> allow = 1
+ *
+ * Other examples:
+ *
+ * IFRAME-03:  0100 --> allowed
+ * IFRAME-04:  1001 --> allowed
+ * IFRAME-05:  1101 --> allowed but its not for us!!!

+ * RF Buffer register
+ *
+ * There are some special control registers on the RF chip
+ * that hold various operation settings related mostly to
+ * the analog parts (channel, gain adjustment etc).
+ *
+ * We don't write on those registers directly but
+ * we send a data packet on the buffer register and
+ * then write on another special register to notify hw
+ * to apply the settings. This is done so that control registers
+ * can be dynamicaly programmed during operation and the settings
+ * are applied faster on the hw.
+ *
+ * We sent such data packets during rf initialization and channel change
+ * through ath5k_hw_rf*_rfregs and ath5k_hw_rf*_channel functions.
+ *
+ * The data packets we send during initializadion are inside ath5k_ini_rf
+ * struct (see ath5k_hw.h) and each one is related to an "rf register bank".
+ * We use *rfregs functions to modify them  acording to current operation
+ * mode and eeprom values and pass them all together to the chip.
+ *
+ * It's obvious from the code that 0x989c is the buffer register but
+ * for the other special registers that we write to after sending each
+ * packet, i have no idea. So i'll name them BUFFER_CONTROL_X registers
+ * for now. It's interesting that they are also used for some other operations.
+ *
+ * Also check out hw.h and U.S. Patent 6677779 B1 (about buffer
+ * registers and control registers):
