If no lower rate available, switch to 2198 * legacy mode (no HT40 channel, no MIMO, no short guard interval). 2199 * c) If using MIMO, set command's mimo_delimiter to number of entries 2200 * using MIMO (3 or 6). 2201 * d) After trying 2 HT rates, switch to legacy mode (no HT40 channel, 2202 * no MIMO, no short guard interval), at the next lower bit rate 2203 * (e.g. if second HT bit rate was 54, try 48 legacy), and follow 2204 * legacy procedure for remaining table entries. 2205 * 2206 * 2) If using legacy initial rate: 2207 * a) Use the initial rate for only one entry. 2208 * b) For each following entry, reduce the rate to next lower available 2209 * rate, until reaching the lowest available rate. 2210 * c) When reducing rate, also switch antenna selection. 2211 * d) Once lowest available rate is reached, repeat this rate until 2212 * rate table is filled (16 entries), switching antenna each entry. 2213 * 2214 * 2215 * ACCUMULATING HISTORY 2216 * 2217 * The rate scaling algorithm for agn devices, as implemented in Linux driver, 2218 * uses two sets of frame Tx success history: One for the current/active 2219 * modulation mode, and one for a speculative/search mode that is being 2220 * attempted. If the speculative mode turns out to be more effective (i.e. 2221 * actual transfer rate is better), then the driver continues to use the 2222 * speculative mode as the new current active mode. 2223 * 2224 * Each history set contains, separately for each possible rate, data for a 2225 * sliding window of the 62 most recent tx attempts at that rate. The data 2226 * includes a shifting bitmap of success(1)/failure(0), and sums of successful 2227 * and attempted frames, from which the driver can additionally calculate a 2228 * success ratio (success / attempted) and number of failures 2229 * (attempted - success), and control the size of the window (attempted). 2230 * The driver uses the bit map to remove successes from the success sum, as 2231 * the oldest tx attempts fall out of the window. 2232 * 2233 * When the agn device makes multiple tx attempts for a given frame, each 2234 * attempt might be at a different rate, and have different modulation 2235 * characteristics (e.g. antenna, fat channel, short guard interval), as set 2236 * up in the rate scaling table in the Link Quality command. The driver must 2237 * determine which rate table entry was used for each tx attempt, to determine 2238 * which rate-specific history to update, and record only those attempts that 2239 * match the modulation characteristics of the history set. 2240 * 2241 * When using block-ack (aggregation), all frames are transmitted at the same 2242 * rate, since there is no per-attempt acknowledgment from the destination 2243 * station. The Tx response struct iwl_tx_resp indicates the Tx rate in 2244 * rate_n_flags field. After receiving a block-ack, the driver can update 2245 * history for the entire block all at once. 2246 * 2247 * 2248 * FINDING BEST STARTING RATE: 2249 * 2250 * When working with a selected initial modulation mode (see below), the 2251 * driver attempts to find a best initial rate. The initial rate is the 2252 * first entry in the Link Quality command's rate table. 2253 * 2254 * 1) Calculate actual throughput (success ratio * expected throughput, see 2255 * table below) for current initial rate. Do this only if enough frames 2256 * have been attempted to make the value meaningful: at least 6 failed 2257 * tx attempts, or at least 8 successes. If not enough, don't try rate 2258 * scaling yet. 2259 * 2260 * 2) Find available rates adjacent to current initial rate. Available means: 2261 * a) supported by hardware && 2262 * b) supported by association && 2263 * c) within any constraints selected by user 2264 * 2265 * 3) Gather measured throughputs for adjacent rates. These might not have 2266 * enough history to calculate a throughput. That's okay, we might try 2267 * using one of them anyway! 2268 * 2269 * 4) Try decreasing rate if, for current rate: 2270 * a) success ratio is < 15% || 2271 * b) lower adjacent rate has better measured throughput || 2272 * c) higher adjacent rate has worse throughput, and lower is unmeasured 2273 * 2274 * As a sanity check, if decrease was determined above, leave rate 2275 * unchanged if: 2276 * a) lower rate unavailable 2277 * b) success ratio at current rate > 85% (very good) 2278 * c) current measured throughput is better than expected throughput 2279 * of lower rate (under perfect 100% tx conditions, see table below) 2280 * 2281 * 5) Try increasing rate if, for current rate: 2282 * a) success ratio is < 15% || 2283 * b) both adjacent rates' throughputs are unmeasured (try it!) || 2284 * b) higher adjacent rate has better measured throughput || 2285 * c) lower adjacent rate has worse throughput, and higher is unmeasured 2286 * 2287 * As a sanity check, if increase was determined above, leave rate 2288 * unchanged if: 2289 * a) success ratio at current rate < 70%. This is not particularly 2290 * good performance; higher rate is sure to have poorer success. 2291 * 2292 * 6) Re-evaluate the rate after each tx frame. If working with block- 2293 * acknowledge, history and statistics may be calculated for the entire 2294 * block (including prior history that fits within the history windows), 2295 * before re-evaluation. 2296 * 2297 * FINDING BEST STARTING MODULATION MODE: 2298 * 2299 * After working with a modulation mode for a "while" (and doing rate scaling), 2300 * the driver searches for a new initial mode in an attempt to improve 2301 * throughput. The "while" is measured by numbers of attempted frames: 2302 * 2303 * For legacy mode, search for new mode after: 2304 * 480 successful frames, or 160 failed frames 2305 * For high-throughput modes (SISO or MIMO), search for new mode after: 2306 * 4500 successful frames, or 400 failed frames 2307 * 2308 * Mode switch possibilities are (3 for each mode): 2309 * 2310 * For legacy: 2311 * Change antenna, try SISO (if HT association), try MIMO (if HT association) 2312 * For SISO: 2313 * Change antenna, try MIMO, try shortened guard interval (SGI) 2314 * For MIMO: 2315 * Try SISO antenna A, SISO antenna B, try shortened guard interval (SGI) 2316 * 2317 * When trying a new mode, use the same bit rate as the old/current mode when 2318 * trying antenna switches and shortened guard interval. When switching to 2319 * SISO from MIMO or legacy, or to MIMO from SISO or legacy, use a rate 2320 * for which the expected throughput (under perfect conditions) is about the 2321 * same or slightly better than the actual measured throughput delivered by 2322 * the old/current mode. 2323 * 2324 * Actual throughput can be estimated by multiplying the expected throughput 2325 * by the success ratio (successful / attempted tx frames). Frame size is 2326 * not considered in this calculation; it assumes that frame size will average 2327 * out to be fairly consistent over several samples.

The max_out_time and suspend_time control the ratio of how 2876 * long the device stays on an associated network channel ("service channel") 2877 * vs. how long it's away from the service channel, i.e. tuned to other channels 2878 * for scanning. 2879 * 2880 * max_out_time is the max time off-channel (in usec), and suspend_time 2881 * is how long (in "extended beacon" format) that the scan is "suspended" 2882 * after returning to the service channel. That is, suspend_time is the 2883 * time that we stay on the service channel, doing normal work, between 2884 * scan segments. The driver may set these parameters differently to support 2885 * scanning when associated vs. not associated, and light vs. heavy traffic 2886 * loads when associated. 2887 * 2888 * After receiving this command, the device's scan engine does the following; 2889 * 2890 * 1) Sends SCAN_START notification to driver 2891 * 2) Checks to see if it has time to do scan for one channel 2892 * 3) Sends NULL packet, with power-save (PS) bit set to 1, 2893 * to tell AP that we're going off-channel 2894 * 4) Tunes to first channel in scan list, does active or passive scan 2895 * 5) Sends SCAN_RESULT notification to driver 2896 * 6) Checks to see if it has time to do scan on *next* channel in list 2897 * 7) Repeats 4-6 until it no longer has time to scan the next channel 2898 * before max_out_time expires 2899 * 8) Returns to service channel 2900 * 9) Sends NULL packet with PS=0 to tell AP that we're back 2901 * 10) Stays on service channel until suspend_time expires 2902 * 11) Repeats entire process 2-10 until list is complete 2903 * 12) Sends SCAN_COMPLETE notification 2904 * 2905 * For fast, efficient scans, the scan command also has support for staying on 2906 * a channel for just a short time, if doing active scanning and getting no 2907 * responses to the transmitted probe request. This time is controlled by 2908 * quiet_time, and the number of received packets below which a channel is 2909 * considered "quiet" is controlled by quiet_plcp_threshold. 2910 * 2911 * For active scanning on channels that have regulatory restrictions against 2912 * blindly transmitting, the scan can listen before transmitting, to make sure 2913 * that there is already legitimate activity on the channel. If enough 2914 * packets are cleanly received on the channel (controlled by good_CRC_th, 2915 * typical value 1), the scan engine starts transmitting probe requests. 2916 * 2917 * Driver must use separate scan commands for 2.4 vs. 5 GHz bands. 2918 * 2919 * To avoid uCode errors, see timing restrictions described under 2920 * struct iwl_scan_channel. 2921 */ 2922 2923 struct iwl3945_scan_cmd { 2924 __le16 len; 2925 u8 reserved0; 2926 u8 channel_count; /* # channels in channel list */ 2927 __le16 quiet_time; /* dwell only this # millisecs on quiet channel 2928 * (only for active scan) */ 2929 __le16 quiet_plcp_th; /* quiet chnl is < this # pkts (typ. 1) */ 2930 __le16 good_CRC_th; /* passive -> active promotion threshold */ 2931 __le16 reserved1; 2932 __le32 max_out_time; /* max usec to be away from associated (service) 2933 * channel */ 2934 __le32 suspend_time; /* pause scan this long (in "extended beacon 2935 * format") when returning to service channel: 2936 * 3945; 31:24 # beacons, 19:0 additional usec, 2937 * 4965; 31:22 # beacons, 21:0 additional usec. 2938 */ 2939 __le32 flags; /* RXON_FLG_* */ 2940 __le32 filter_flags; /* RXON_FILTER_* */ 2941 2942 /* For active scans (set to all-0s for passive scans). 2943 * Does not include payload.
