ATL1 ETHERNET DRIVER
P: Jay Cliburn
M: jcliburn@gmail.com
If you choose to build a module, it'll be called p54pci.
+config ATH5K
+ tristate "Atheros 5xxx wireless cards support"
+ depends on PCI && MAC80211 && WLAN_80211 && EXPERIMENTAL
+ ---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.

+ * 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.

+ * @AR5K_INT_RXNOFRM: No frame received (?)
+ * @AR5K_INT_RXEOL: received End Of List for VEOL (Virtual End Of List). The

+ * LinkPtr is NULL. For more details, refer to:
+ * http://www.freepatentsonline.com/20030225739.html
+ * @AR5K_INT_RXORN: Indicates we got RX overrun (eg. no more descriptors).
+ * Note that Rx overrun is not always fatal, on some chips we can continue
+ * operation without reseting the card, that's why int_fatal is not
+ * common for all chips.
+ * @AR5K_INT_TX: mask to identify received frame interrupts, of type
+ * AR5K_ISR_TXOK or AR5K_ISR_TXERR
+ * @AR5K_INT_TXDESC: Request TX descriptor/Read TX status descriptor (?)
+ * @AR5K_INT_TXURN: received when we should increase the TX trigger threshold
+ * We currently do increments on interrupt by
+ * (AR5K_TUNE_MAX_TX_FIFO_THRES - current_trigger_level) / 2
+ * @AR5K_INT_MIB: Indicates the Management Information Base counters should be
+ * checked. We should do this with ath5k_hw_update_mib_counters() but
+ * it seems we should also then do some noise immunity work.
+ * @AR5K_INT_RXPHY: RX PHY Error
+ * @AR5K_INT_RXKCM: ??
+ * @AR5K_INT_SWBA: SoftWare Beacon Alert - indicates its time to send a
+ * beacon that must be handled in software. The alternative is if you
+ * have VEOL support, in that case you let the hardware deal with things.
+ * @AR5K_INT_BMISS: If in STA mode this indicates we have stopped seeing
+ * beacons from the AP have associated with, we should probably try to
+ * reassociate. When in IBSS mode this might mean we have not received
+ * any beacons from any local stations. Note that every station in an
+ * IBSS schedules to send beacons at the Target Beacon Transmission Time
+ * (TBTT) with a random backoff.
+ * @AR5K_INT_BNR: Beacon Not Ready interrupt - ??
+ * @AR5K_INT_GPIO: GPIO interrupt is used for RF Kill, disabled for now
+ * until properly handled
+ * @AR5K_INT_FATAL: Fatal errors were encountered, typically caused by DMA
+ * errors. These types of errors we can enable seem to be of type
+ * AR5K_SIMR2_MCABT, AR5K_SIMR2_SSERR and AR5K_SIMR2_DPERR.
+ * @AR5K_INT_GLOBAL: Seems to be used to clear and set the IER
+ * @AR5K_INT_NOCARD: signals the card has been removed
+ * @AR5K_INT_COMMON: common interrupts shared amogst MACs with the same
+ * bit value
+ *
+ * These are mapped to take advantage of some common bits
+ * between the MACs, to be able to set intr properties
+ * easier. Some of them are not used yet inside hw.c. Most map

+/**
+ * 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):
