+ NOTE: In order to authenticate connections you have to select

+
+ DRBD is a shared-nothing, synchronously replicated block device. It
+ is designed to serve as a building block for high availability
+ clusters and in this context, is a "drop-in" replacement for shared
+ storage. Simplistically, you could see it as a network RAID 1.
+
+ Each minor device has a role, which can be 'primary' or 'secondary'.
+ On the node with the primary device the application is supposed to
+ run and to access the device (/dev/drbdX). Every write is sent to
+ the local 'lower level block device' and, across the network, to the
+ node with the device in 'secondary' state. The secondary device
+ simply writes the data to its lower level block device.
+
+ DRBD can also be used in dual-Primary mode (device writable on both
+ nodes), which means it can exhibit shared disk semantics in a
+ shared-nothing cluster. Needless to say, on top of dual-Primary
+ DRBD utilizing a cluster file system is necessary to maintain for
+ cache coherency.
+
+ For automatic failover you need a cluster manager (e.g. heartbeat).

+ * At a granularity of 4KiB storage represented per bit,
+ * and stroage sizes of several TiB,
+ * and possibly small-bandwidth replication,
+ * the bitmap transfer time can take much too long,
+ * if transmitted in plain text.
+ *
+ * We try to reduce the transfered bitmap information
+ * by encoding runlengths of bit polarity.
+ *
+ * We never actually need to encode a "zero" (runlengths are positive).
+ * But then we have to store the value of the first bit.
+ * The first bit of information thus shall encode if the first runlength
+ * gives the number of set or unset bits.
+ *
+ * We assume that large areas are either completely set or unset,
+ * which gives good compression with any runlength method,
+ * even when encoding the runlength as fixed size 32bit/64bit integers.
+ *
+ * Still, there may be areas where the polarity flips every few bits,
+ * and encoding the runlength sequence of those areas with fix size
+ * integers would be much worse than plaintext.
+ *
+ * We want to encode small runlength values with minimum code length,
+ * while still being able to encode a Huge run of all zeros.
+ *
+ * Thus we need a Variable Length Integer encoding, VLI.
+ *
+ * For some cases, we produce more code bits than plaintext input.
+ * We need to send incompressible chunks as plaintext, skip over them
+ * and then see if the next chunk compresses better.
+ *
+ * We don't care too much about "excellent" compression ratio for large
+ * runlengths (all set/all clear): whether we achieve a factor of 100
+ * or 1000 is not that much of an issue.
+ * We do not want to waste too much on short runlengths in the "noisy"
+ * parts of the bitmap, though.
+ *
+ * There are endless variants of VLI, we experimented with:
+ * * simple byte-based
+ * * various bit based with different code word length.
+ *
+ * To avoid yet an other configuration parameter (choice of bitmap compression
+ * algorithm) which was difficult to explain and tune, we just chose the one
+ * variant that turned out best in all test cases.
+ * Based on real world usage patterns, with device sizes ranging from a few GiB
+ * to several TiB, file server/mailserver/webserver/mysql/postgress,
+ * mostly idle to really busy, the all time winner (though sometimes only
+ * marginally better) is:

+ *
+ * this particular encoding is chosen so that the prefix code
+ * starts as unary encoding the level, then modified so that
+ * 10 levels can be described in 8bit, with minimal overhead
+ * for the smaller levels.
+ *

- *
- * Falcon hardware access
- *
- **************************************************************************
- *
- * Notes on locking strategy:
- *
- * Most Falcon registers require 16-byte (or 8-byte, for SRAM
- * registers) atomic writes which necessitates locking.
- * Under normal operation few writes to the Falcon BAR are made and these
- * registers (EVQ_RPTR_REG, RX_DESC_UPD_REG and TX_DESC_UPD_REG) are special
- * cased to allow 4-byte (hence lockless) accesses.
- *
- * It *is* safe to write to these 4-byte registers in the middle of an
- * access to an 8-byte or 16-byte register. We therefore use a
- * spinlock to protect accesses to the larger registers, but no locks
- * for the 4-byte registers.
- *
- * A write barrier is needed to ensure that DW3 is written after DW0/1/2
- * due to the way the 16byte registers are "collected" in the Falcon BIU
- *
- * We also lock when carrying out reads, to ensure consistency of the
- * data (made possible since the BIU reads all 128 bits into a cache).
- * Reads are very rare, so this isn't a significant performance
- * impact. (Most data transferred from NIC to host is DMAed directly
- * into host memory).
- *
- * I/O BAR access uses locks for both reads and writes (but is only provided
- * for testing purposes).

+ **************************************************************************
+ *
+ * Notes on locking strategy:
+ *
+ * Most NIC registers require 16-byte (or 8-byte, for SRAM) atomic writes
+ * which necessitates locking.
+ * Under normal operation few writes to NIC registers are made and these
+ * registers (EVQ_RPTR_REG, RX_DESC_UPD_REG and TX_DESC_UPD_REG) are special
+ * cased to allow 4-byte (hence lockless) accesses.
+ *
+ * It *is* safe to write to these 4-byte registers in the middle of an
+ * access to an 8-byte or 16-byte register. We therefore use a
+ * spinlock to protect accesses to the larger registers, but no locks
+ * for the 4-byte registers.
+ *
+ * A write barrier is needed to ensure that DW3 is written after DW0/1/2
+ * due to the way the 16byte registers are "collected" in the BIU.
+ *
+ * We also lock when carrying out reads, to ensure consistency of the
+ * data (made possible since the BIU reads all 128 bits into a cache).
+ * Reads are very rare, so this isn't a significant performance
+ * impact. (Most data transferred from NIC to host is DMAed directly
+ * into host memory).
+ *
+ * I/O BAR access uses locks for both reads and writes (but is only provided
+ * for testing purposes).

- * ath5k_hw_set_bssid_mask - filter out bssids we listen
- *
- * @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!!!

+ * ath9k_hw_updatetxtriglevel - adjusts the frame trigger level
+ *
+ * @ah: atheros hardware struct
+ * @bIncTrigLevel: whether or not the frame trigger level should be updated
+ *
+ * The frame trigger level specifies the minimum number of bytes,
+ * in units of 64 bytes, that must be DMA'ed into the PCU TX FIFO
+ * before the PCU will initiate sending the frame on the air. This can
+ * mean we initiate transmit before a full frame is on the PCU TX FIFO.
+ * Resets to 0x1 (meaning 64 bytes or a full frame, whichever occurs
+ * first)
+ *
+ * Caution must be taken to ensure to set the frame trigger level based
+ * on the DMA request size. For example if the DMA request size is set to
+ * 128 bytes the trigger level cannot exceed 6 * 64 = 384. This is because
+ * there need to be enough space in the tx FIFO for the requested transfer
+ * size. Hence the tx FIFO will stop with 512 - 128 = 384 bytes. If we set
+ * the threshold to a value beyond 6, then the transmit will hang.
+ *
+ * Current dual stream devices have a PCU TX FIFO size of 8 KB.
+ * Current single stream devices have a PCU TX FIFO size of 4 KB, however,
+ * there is a hardware issue which forces us to use 2 KB instead so the
+ * frame trigger level must not exceed 2 KB for these chipsets.

+ * ath_hw_set_bssid_mask - filter out bssids we listen
+ *
+ * @common: the ath_common struct for the device.
+ *
+ * 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
+ *

+IWCONFIG COMMANDS
+========================
+power period
+
+ This command is used to configure the station in deep sleep mode /
+ auto deep sleep mode.
+
+ The timer is implemented to monitor the activities (command, event,
+ etc.). When an activity is detected station will exit from deep
+ sleep mode automatically and restart the timer. At timer expiry
+ (no activity for defined time period) the deep sleep mode is entered
+ automatically.
+
+ Note: this command is for SDIO interface only.
+
+ Usage:
+ To enable deep sleep mode do:
+ iwconfig wlan0 power period 0
+ To enable auto deep sleep mode with idle time period 5 seconds do:
+ iwconfig wlan0 power period 5
+ To disable deep sleep/auto deep sleep mode do:
+ iwconfig wlan0 power period -1

+ tristate "Aironet Arlan 655 & IC2200 DS support"
+ depends on ISA && !64BIT && WLAN
+ select WIRELESS_EXT
+ ---help---
+ Aironet makes Arlan, a class of wireless LAN adapters. These use the
+ www.Telxon.com chip, which is also used on several similar cards.
+ This driver is tested on the 655 and IC2200 series cards. Look at
+ <http://www.ylenurme.ee/~elmer/655/> for the latest information.
+
+ The driver is built as two modules, arlan and arlan-proc. The latter
+ is the /proc interface and is not needed most of time.
+
+ On some computers the card ends up in non-valid state after some
+ time. Use a ping-reset script to clear it.

+ ---help---
+ Say Y if you have a Metricom radio and intend to use Starmode Radio
+ IP. STRIP is a radio protocol developed for the MosquitoNet project
+ to send Internet traffic using Metricom radios. Metricom radios are
+ small, battery powered, 100kbit/sec packet radio transceivers, about
+ the size and weight of a cellular telephone. (You may also have heard
+ them called "Metricom modems" but we avoid the term "modem" because
+ it misleads many people into thinking that you can plug a Metricom
+ modem into a phone line and use it as a modem.)
+
+ You can use STRIP on any Linux machine with a serial port, although
+ it is obviously most useful for people with laptop computers. If you
+ think you might get a Metricom radio in the future, there is no harm
+ in saying Y to STRIP now, except that it makes the kernel a bit
+ bigger.
+
+ To compile this as a module, choose M here: the module will be
+ called strip.
