* Tx Commands & Responses:

+ * Driver must place each REPLY_TX command into one of the prioritized Tx
+ * queues in host DRAM, shared between driver and device. When the device's
+ * Tx scheduler and uCode are preparing to transmit, the device pulls the
+ * Tx command over the PCI bus via one of the device's Tx DMA channels,
+ * to fill an internal FIFO from which data will be transmitted.
+ *
+ * uCode handles all timing and protocol related to control frames
+ * (RTS/CTS/ACK), based on flags in the Tx command.
+ *
+ * uCode handles retrying Tx when an ACK is expected but not received.
+ * This includes trying lower data rates than the one requested in the Tx
+ * command, as set up by the REPLY_RATE_SCALE (for 3945) or
+ * REPLY_TX_LINK_QUALITY_CMD (4965).
+ *
+ * Driver sets up transmit power for various rates via REPLY_TX_PWR_TABLE_CMD.

* 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.
