+config ATH5K

+ select ATH_COMMON
+ select MAC80211_LEDS
+ select LEDS_CLASS
+ select NEW_LEDS
+ ---help---
+ This module adds support for wireless adapters based on
+ Atheros 5xxx chipset.
+
+ Currently the following chip versions are supported:
+
+ MAC: AR5211 AR5212
+ PHY: RF5111/2111 RF5112/2112 RF5413/2413
+
+ This driver uses the kernel's mac80211 subsystem.
+
+ If you choose to build a module, it'll be called ath5k. Say M if
+ unsure.
+
+config ATH5K_DEBUG
+ bool "Atheros 5xxx debugging"
+ depends on ATH5K
+ ---help---
+ Atheros 5xxx debugging messages.
+
+ Say Y, if and you will get debug options for ath5k.
+ To use this, you need to mount debugfs:
+
+ mkdir /debug/
+ mount -t debugfs debug /debug/
+
+ You will get access to files under:
+ /debug/ath5k/phy0/
+
+ To enable debug, pass the debug level to the debug module
+ parameter. For example:
+
+ modprobe ath5k debug=0x00000400

+ * 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.

+ *
+ * @ah: the &struct ath5k_hw
+ * @mask: the bssid_mask, a u8 array of size ETH_ALEN
+ *
+ * BSSID masking is a method used by AR5212 and newer hardware to inform PCU
+ * which bits of the interface's MAC address should be looked at when trying
+ * to decide which packets to ACK. In station mode and AP mode with a single
+ * BSS every bit matters since we lock to only one BSS. In AP mode with
+ * multiple BSSes (virtual interfaces) not every bit matters because hw must
+ * accept frames for all BSSes and so we tweak some bits of our mac address
+ * in order to have multiple BSSes.
+ *
+ * NOTE: This is a simple filter and does *not* filter out all
+ * relevant frames. Some frames that are not for us might get ACKed from us
+ * by PCU because they just match the mask.
+ *
+ * When handling multiple BSSes you can get the BSSID mask by computing the
+ * set of ~ ( MAC XOR BSSID ) for all bssids we handle.
+ *
+ * When you do this you are essentially computing the common bits of all your
+ * BSSes. Later it is assumed the harware will "and" (&) the BSSID mask with
+ * the MAC address to obtain the relevant bits and compare the result with
+ * (frame's BSSID & mask) to see if they match.
+ */
+/*
+ * 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!!!

+ * There are some special registers on the RF chip

+ * the analog parts (channel, gain adjustment etc).
+ *
+ * We don't write on those registers directly but
+ * we send a data packet on the chip, using a special register,
+ * that holds all the settings we need. After we 've sent the
+ * data packet, we 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 call each data packet an "RF Bank" and all the data we write
+ * (all RF Banks) "RF Buffer". This file holds initial RF Buffer
+ * data for the different RF chips, and various info to match RF
+ * Buffer offsets with specific RF registers so that we can access
+ * them. We tweak these settings on rfregs_init function.
