* For agn devices
*
* Each station in the agn device ' s internal station table has its own table
* of 16
* Tx rates and modulation modes ( e . g . legacy / SISO / MIMO ) for retrying Tx when
* an ACK is not received . This command replaces the entire table for
* one station .
*
* NOTE : Station must already be in agn device ' s station table .
* Use REPLY_ADD_STA .
*
* The rate scaling procedures described below work well . Of course , other
* procedures are possible , and may work better for particular environments .
*
*
* FILLING THE RATE TABLE
*
* Given a particular initial rate and mode , as determined by the rate
* scaling algorithm described below , the Linux driver uses the following
* formula to fill the rs_table [ LINK_QUAL_MAX_RETRY_NUM ] rate table in the
* Link Quality command :
*
*
* 1 ) If using High - throughput ( HT ) ( SISO or MIMO ) initial rate :
* a ) Use this same initial rate for first 3 entries .
* b ) Find next lower available rate using same mode ( SISO or MIMO ) ,
* use for next 3 entries . If no lower rate available , switch to
* legacy mode ( no HT40 channel , no MIMO , no short guard interval ) .
* c ) If using MIMO , set command ' s mimo_delimiter to number of entries
* using MIMO ( 3 or 6 ) .
* d ) After trying 2 HT rates , switch to legacy mode ( no HT40 channel ,
* no MIMO , no short guard interval ) , at the next lower bit rate
* ( e . g . if second HT bit rate was 54 , try 48 legacy ) , and follow
* legacy procedure for remaining table entries .
*
* 2 ) If using legacy initial rate :
* a ) Use the initial rate for only one entry .
* b ) For each following entry , reduce the rate to next lower available
* rate , until reaching the lowest available rate .
* c ) When reducing rate , also switch antenna selection .
* d ) Once lowest available rate is reached , repeat this rate until
* rate table is filled ( 16 entries ) , switching antenna each entry .
*
*
* ACCUMULATING HISTORY
*
* The rate scaling algorithm for agn devices , as implemented in Linux driver ,
* uses two sets of frame Tx success history : One for the current / active
* modulation mode , and one for a speculative / search mode that is being
* attempted . If the speculative mode turns out to be more effective ( i . e .
* actual transfer rate is better ) , then the driver continues to use the
* speculative mode as the new current active mode .
*
* Each history set contains , separately for each possible rate , data for a
* sliding window of the 62 most recent tx attempts at that rate . The data
* includes a shifting bitmap of success ( 1 ) / failure ( 0 ) , and sums of successful
* and attempted frames , from which the driver can additionally calculate a
* success ratio ( success / attempted ) and number of failures
* ( attempted - success ) , and control the size of the window ( attempted ) .
* The driver uses the bit map to remove successes from the success sum , as
* the oldest tx attempts fall out of the window .
*
* When the agn device makes multiple tx attempts for a given frame , each
* attempt might be at a different rate , and have different modulation
* characteristics ( e . g . antenna , fat channel , short guard interval ) , as set
* up in the rate scaling table in the Link Quality command . The driver must
* determine which rate table entry was used for each tx attempt , to determine
* which rate - specific history to update , and record only those attempts that
* match the modulation characteristics of the history set .
*
* When using block - ack ( aggregation ) , all frames are transmitted at the same
* rate , since there is no per - attempt acknowledgment from the destination
* station . The Tx response struct iwl_tx_resp indicates the Tx rate in
* rate_n_flags field . After receiving a block - ack , the driver can update
* history for the entire block all at once .
*
*
* FINDING BEST STARTING RATE :
*
* When working with a selected initial modulation mode ( see below ) , the
* driver attempts to find a best initial rate . The initial rate is the
* first entry in the Link Quality command ' s rate table .
*
* 1 ) Calculate actual throughput ( success ratio * expected throughput , see
* table below ) for current initial rate . Do this only if enough frames
* have been attempted to make the value meaningful : at least 6 failed
* tx attempts , or at least 8 successes . If not enough , don ' t try rate
* scaling yet .
*
* 2 ) Find available rates adjacent to current initial rate . Available means :
* a ) supported by hardware & &
* b ) supported by association & &
* c ) within any constraints selected by user
*
* 3 ) Gather measured throughputs for adjacent rates . These might not have
* enough history to calculate a throughput . That ' s okay , we might try
* using one of them anyway !
*
* 4 ) Try decreasing rate if , for current rate :
* a ) success ratio is < 15 % | |
* b ) lower adjacent rate has better measured throughput | |
* c ) higher adjacent rate has worse throughput , and lower is unmeasured
*
* As a sanity check , if decrease was determined above , leave rate
* unchanged if :
* a ) lower rate unavailable
* b ) success ratio at current rate > 85 % ( very good )
* c ) current measured throughput is better than expected throughput
* of lower rate ( under perfect 100 % tx conditions , see table below )
*
* 5 ) Try increasing rate if , for current rate :
* a ) success ratio is < 15 % | |
* b ) both adjacent rates ' throughputs are unmeasured ( try it ! ) | |
* b ) higher adjacent rate has better measured throughput | |
* c ) lower adjacent rate has worse throughput , and higher is unmeasured
*
* As a sanity check , if increase was determined above , leave rate
* unchanged if :
* a ) success ratio at current rate < 70 % . This is not particularly
* good performance ; higher rate is sure to have poorer success .
*
* 6 ) Re - evaluate the rate after each tx frame . If working with block -
* acknowledge , history and statistics may be calculated for the entire
* block ( including prior history that fits within the history windows ) ,
* before re - evaluation .
*
* FINDING BEST STARTING MODULATION MODE :
*
* After working with a modulation mode for a " while " ( and doing rate scaling ) ,
* the driver searches for a new initial mode in an attempt to improve
* throughput . The " while " is measured by numbers of attempted frames :
*
* For legacy mode , search for new mode after :
* 480 successful frames , or 160 failed frames
* For high - throughput modes ( SISO or MIMO ) , search for new mode after :
* 4500 successful frames , or 400 failed frames
*
* Mode switch possibilities are ( 3 for each mode ) :
*
* For legacy :
* Change antenna , try SISO ( if HT association ) , try MIMO ( if HT association )
* For SISO :
* Change antenna , try MIMO , try shortened guard interval ( SGI )
* For MIMO :
* Try SISO antenna A , SISO antenna B , try shortened guard interval ( SGI )
*
* When trying a new mode , use the same bit rate as the old / current mode when
* trying antenna switches and shortened guard interval . When switching to
* SISO from MIMO or legacy , or to MIMO from SISO or legacy , use a rate
* for which the expected throughput ( under perfect conditions ) is about the
* same or slightly better than the actual measured throughput delivered by
* the old / current mode .
*
* Actual throughput can be estimated by multiplying the expected throughput
* by the success ratio ( successful / attempted tx frames ) . Frame size is
* not considered in this calculation ; it assumes that frame size will average
* out to be fairly consistent over several samples . The following are
* metric values for expected throughput assuming 100 % success ratio .
* Only G band has support for CCK rates :
*
* RATE : 1 2 5 11 6 9 12 18 24 36 48 54 60
*
* G : 7 13 35 58 40 57 72 98 121 154 177 186 186

* SGI SISO 20 MHz : 0 0 0 0 46 46 82 110 132 168 192 202 211
* MIMO 20 MHz : 0 0 0 0 74 74 123 155 179 214 236 244 251
* SGI MIMO 20 MHz : 0 0 0 0 81 81 131 164 188 222 243 251 257
* SISO 40 MHz : 0 0 0 0 77 77 127 160 184 220 242 250 257
* SGI SISO 40 MHz : 0 0 0 0 83 83 135 169 193 229 250 257 264
* MIMO 40 MHz : 0 0 0 0 123 123 182 214 235 264 279 285 289
* SGI MIMO 40 MHz : 0 0 0 0 131 131 191 222 242 270 284 289 293
*
* After the new mode has been tried for a short while ( minimum of 6 failed
* frames or 8 successful frames ) , compare success ratio and actual throughput
* estimate of the new mode with the old . If either is better with the new
* mode , continue to use the new mode .
*
* Continue comparing modes until all 3 possibilities have been tried .
* If moving from legacy to HT , try all 3 possibilities from the new HT
* mode . After trying all 3 , a best mode is found . Continue to use this mode
* for the longer " while " described above ( e . g . 480 successful frames for
* legacy ) , and then repeat the search process .

/*
* REPLY_SCAN_CMD = 0 x80 ( 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 , i . e . 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 iwl_scan_channel .

* With the uCode used for open source drivers , most Tx calibration ( except

* 2 ) Receiver gain balance ( optimize MIMO , and detect disconnected antennas )
* 3 ) Receiver sensitivity ( to optimize signal detection )
*
*****************************************************************************/
/*
* SENSITIVITY_CMD = 0 xa8 ( command , has simple generic response )
*
* This command sets up the Rx signal detector for a sensitivity level that
* is high enough to lock onto all signals within the associated network ,
* but low enough to ignore signals that are below a certain threshold , so as
* not to have too many " false alarms " . False alarms are signals that the
* Rx DSP tries to lock onto , but then discards after determining that they
* are noise .
*
* The optimum number of false alarms is between 5 and 50 per 200 TUs
* ( 200 * 1024 uSecs , i . e . 204 . 8 milliseconds ) of actual Rx time ( i . e .
* time listening , not transmitting ) . Driver must adjust sensitivity so that
* the ratio of actual false alarms to actual Rx time falls within this range .
*
* While associated , uCode delivers STATISTICS_NOTIFICATIONs after each
* received beacon . These provide information to the driver to analyze the
* sensitivity . Don ' t analyze statistics that come in from scanning , or any
* other non - associated - network source . Pertinent statistics include :
*
* From " general " statistics ( struct statistics_rx_non_phy ) :
*
* ( beacon_energy_ [ abc ] & 0 x0FF00 ) > > 8 ( unsigned , higher value is lower level )
* Measure of energy of desired signal . Used for establishing a level
* below which the device does not detect signals .
*
* ( beacon_silence_rssi_ [ abc ] & 0 x0FF00 ) > > 8 ( unsigned , units in dB )
* Measure of background noise in silent period after beacon .
*
* channel_load
* uSecs of actual Rx time during beacon period ( varies according to
* how much time was spent transmitting ) .
*
* From " cck " and " ofdm " statistics ( struct statistics_rx_phy ) , separately :
*
* false_alarm_cnt
* Signal locks abandoned early ( before phy - level header ) .
*
* plcp_err
* Signal locks abandoned late ( during phy - level header ) .
*
* NOTE : Both false_alarm_cnt and plcp_err increment monotonically from
* beacon to beacon , i . e . each value is an accumulation of all errors
* before and including the latest beacon . Values will wrap around to 0
* after counting up to 2 ^ 32 - 1 . Driver must differentiate vs .
* previous beacon ' s values to determine # false alarms in the current
* beacon period .
*
* Total number of false alarms = false_alarms + plcp_errs
*
* For OFDM , adjust the following table entries in struct iwl_sensitivity_cmd
* ( notice that the start points for OFDM are at or close to settings for
* maximum sensitivity ) :
*
* START / MIN / MAX
* HD_AUTO_CORR32_X1_TH_ADD_MIN_INDEX 90 / 85 / 120
* HD_AUTO_CORR32_X1_TH_ADD_MIN_MRC_INDEX 170 / 170 / 210
* HD_AUTO_CORR32_X4_TH_ADD_MIN_INDEX 105 / 105 / 140
* HD_AUTO_CORR32_X4_TH_ADD_MIN_MRC_INDEX 220 / 220 / 270
*
* If actual rate of OFDM false alarms ( + plcp_errors ) is too high
* ( greater than 50 for each 204 . 8 msecs listening ) , reduce sensitivity
* by * adding * 1 to all 4 of the table entries above , up to the max for
* each entry . Conversely , if false alarm rate is too low ( less than 5
* for each 204 . 8 msecs listening ) , * subtract * 1 from each entry to
* increase sensitivity .
*
* For CCK sensitivity , keep track of the following :
*
* 1 ) . 20 - beacon history of maximum background noise , indicated by
* ( beacon_silence_rssi_ [ abc ] & 0 x0FF00 ) , units in dB , across the
* 3 receivers . For any given beacon , the " silence reference " is
* the maximum of last 60 samples ( 20 beacons * 3 receivers ) .
*
* 2 ) . 10 - beacon history of strongest signal level , as indicated
* by ( beacon_energy_ [ abc ] & 0 x0FF00 ) > > 8 , across the 3 receivers ,
* i . e . the strength of the signal through the best receiver at the
* moment . These measurements are " upside down " , with lower values
* for stronger signals , so max energy will be * minimum * value .
*
* Then for any given beacon , the driver must determine the * weakest *
* of the strongest signals ; this is the minimum level that needs to be
* successfully detected , when using the best receiver at the moment .
* " Max cck energy " is the maximum ( higher value means lower energy ! )
* of the last 10 minima . Once this is determined , driver must add
* a little margin by adding " 6 " to it .
*
* 3 ) . Number of consecutive beacon periods with too few false alarms .
* Reset this to 0 at the first beacon period that falls within the
* " good " range ( 5 to 50 false alarms per 204 . 8 milliseconds rx ) .
*
* Then , adjust the following CCK table entries in struct iwl_sensitivity_cmd
* ( notice that the start points for CCK are at maximum sensitivity ) :
*
* START / MIN / MAX
* HD_AUTO_CORR40_X4_TH_ADD_MIN_INDEX 125 / 125 / 200
* HD_AUTO_CORR40_X4_TH_ADD_MIN_MRC_INDEX 200 / 200 / 400
* HD_MIN_ENERGY_CCK_DET_INDEX 100 / 0 / 100
*
* If actual rate of CCK false alarms ( + plcp_errors ) is too high
* ( greater than 50 for each 204 . 8 msecs listening ) , method for reducing
* sensitivity is :
*
* 1 ) * Add * 3 to value in HD_AUTO_CORR40_X4_TH_ADD_MIN_MRC_INDEX ,
* up to max 400 .
*
* 2 ) If current value in HD_AUTO_CORR40_X4_TH_ADD_MIN_INDEX is < 160 ,
* sensitivity has been reduced a significant amount ; bring it up to
* a moderate 161 . Otherwise , * add * 3 , up to max 200 .
*
* 3 ) a ) If current value in HD_AUTO_CORR40_X4_TH_ADD_MIN_INDEX is > 160 ,
* sensitivity has been reduced only a moderate or small amount ;
* * subtract * 2 from value in HD_MIN_ENERGY_CCK_DET_INDEX ,
* down to min 0 . Otherwise ( if gain has been significantly reduced ) ,
* don ' t change the HD_MIN_ENERGY_CCK_DET_INDEX value .
*
* b ) Save a snapshot of the " silence reference " .
*
* If actual rate of CCK false alarms ( + plcp_errors ) is too low
* ( less than 5 for each 204 . 8 msecs listening ) , method for increasing
* sensitivity is used only if :
*
* 1 a ) Previous beacon did not have too many false alarms
* 1 b ) AND difference between previous " silence reference " and current
* " silence reference " ( prev - current ) is 2 or more ,
* OR 2 ) 100 or more consecutive beacon periods have had rate of
* less than 5 false alarms per 204 . 8 milliseconds rx time .
*
* Method for increasing sensitivity :
*
* 1 ) * Subtract * 3 from value in HD_AUTO_CORR40_X4_TH_ADD_MIN_INDEX ,
* down to min 125 .
*
* 2 ) * Subtract * 3 from value in HD_AUTO_CORR40_X4_TH_ADD_MIN_MRC_INDEX ,
* down to min 200 .
*
* 3 ) * Add * 2 to value in HD_MIN_ENERGY_CCK_DET_INDEX , up to max 100 .
*
* If actual rate of CCK false alarms ( + plcp_errors ) is within good range
* ( between 5 and 50 for each 204 . 8 msecs listening ) :
*
* 1 ) Save a snapshot of the silence reference .
*
* 2 ) If previous beacon had too many CCK false alarms ( + plcp_errors ) ,
* give some extra margin to energy threshold by * subtracting * 8
* from value in HD_MIN_ENERGY_CCK_DET_INDEX .
*
* For all cases ( too few , too many , good range ) , make sure that the CCK
* detection threshold ( energy ) is below the energy level for robust
* detection over the past 10 beacon periods , the " Max cck energy " .
* Lower values mean higher energy ; this means making sure that the value
* in HD_MIN_ENERGY_CCK_DET_INDEX is at or * above * " Max cck energy " .
