In this mode, each queue 707 * contains TFDs for a unique combination of Recipient Address (RA) 708 * and Traffic Identifier (TID), that is, traffic of a given 709 * Quality-Of-Service (QOS) priority, destined for a single station. 710 * 711 * In scheduler-ack mode, the scheduler keeps track of the Tx status of 712 * each frame within the BA window, including whether it's been transmitted, 713 * and whether it's been acknowledged by the receiving station.

Using (interpolated) factory gain table index 1653 * as a starting point, adjust this index lower to increase txpower, 1654 * or higher to decrease txpower, until the target txpower is reached. 1655 * Each step in the gain table is 1/2 dB. 1656 * 1657 * For example, if factory measured txpower is 16 dBm, and target txpower 1658 * is 13 dBm, add 6 steps to the factory gain index to reduce txpower 1659 * by 3 dB. 1660 * 1661 * 1662 * 6) Find difference between current device temperature and (interpolated) 1663 * factory-measured temperature for sub-band. Factory values are in 1664 * degrees Celsius. To calculate current temperature, see comments for 1665 * "4965 temperature calculation". 1666 * 1667 * If current temperature is higher than factory temperature, driver must 1668 * increase gain (lower gain table index), and vice versa. 1669 * 1670 * Temperature affects gain differently for different channels: 1671 * 1672 * 2.4 GHz all channels: 3.5 degrees per half-dB step 1673 * 5 GHz channels 34-43: 4.5 degrees per half-dB step 1674 * 5 GHz channels >= 44: 4.0 degrees per half-dB step 1675 * 1676 * NOTE: Temperature can increase rapidly when transmitting, especially 1677 * with heavy traffic at high txpowers.
