| 1288 | * The hardware scan command is very powerful; the driver can set it up to |
| 1289 | * maintain (relatively) normal network traffic while doing a scan in the |
| 1290 | * background. The max_out_time and suspend_time control the ratio of how |
| 1291 | * long the device stays on an associated network channel ("service channel") |
| 1292 | * vs. how long it's away from the service channel, tuned to other channels |
| 1293 | * for scanning. |
| 1294 | * |
| 1295 | * max_out_time is the max time off-channel (in usec), and suspend_time |
| 1296 | * is how long (in "extended beacon" format) that the scan is "suspended" |
| 1297 | * after returning to the service channel. That is, suspend_time is the |
| 1298 | * time that we stay on the service channel, doing normal work, between |
| 1299 | * scan segments. The driver may set these parameters differently to support |
| 1300 | * scanning when associated vs. not associated, and light vs. heavy traffic |
| 1301 | * loads when associated. |
| 1302 | * |
| 1303 | * After receiving this command, the device's scan engine does the following; |
| 1304 | * |
| 1305 | * 1) Sends SCAN_START notification to driver |
| 1306 | * 2) Checks to see if it has time to do scan for one channel |
| 1307 | * 3) Sends NULL packet, with power-save (PS) bit set to 1, |
| 1308 | * to tell AP that we're going off-channel |
| 1309 | * 4) Tunes to first channel in scan list, does active or passive scan |
| 1310 | * 5) Sends SCAN_RESULT notification to driver |
| 1311 | * 6) Checks to see if it has time to do scan on *next* channel in list |
| 1312 | * 7) Repeats 4-6 until it no longer has time to scan the next channel |
| 1313 | * before max_out_time expires |
| 1314 | * 8) Returns to service channel |
| 1315 | * 9) Sends NULL packet with PS=0 to tell AP that we're back |
| 1316 | * 10) Stays on service channel until suspend_time expires |
| 1317 | * 11) Repeats entire process 2-10 until list is complete |
| 1318 | * 12) Sends SCAN_COMPLETE notification |
| 1319 | * |
| 1320 | * For fast, efficient scans, the scan command also has support for staying on |
| 1321 | * a channel for just a short time, if doing active scanning and getting no |
| 1322 | * responses to the transmitted probe request. This time is controlled by |
| 1323 | * quiet_time, and the number of received packets below which a channel is |
| 1324 | * considered "quiet" is controlled by quiet_plcp_threshold. |
| 1325 | * |
| 1326 | * For active scanning on channels that have regulatory restrictions against |
| 1327 | * blindly transmitting, the scan can listen before transmitting, to make sure |
| 1328 | * that there is already legitimate activity on the channel. If enough |
| 1329 | * packets are cleanly received on the channel (controlled by good_CRC_th, |
| 1330 | * typical value 1), the scan engine starts transmitting probe requests. |
| 1331 | * |
| 1332 | * Driver must use separate scan commands for 2.4 vs. 5 GHz bands. |
| 1333 | * |
| 1334 | * To avoid uCode errors, see timing restrictions described under |
| 1335 | * struct iwl3945_scan_channel. |
