- * 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.
