| /* |
| * REPLY_SCAN_CMD = 0x80 (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, 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 iwl3945_scan_channel. |
