final retransmission attempts at progressively lower modulations.
The retransmission mechanism described above does not apply for test frames
sent for evaluating link quality on higher modulations. If the number of HW
retries is lower than 3 or if the initial modulation is lower than 4, the number of
modulations used for retransmission will be limited as shown in

Table 4-16: Examples of Retransmissions on Different Modulation Levels

4.2.6.5.10.3.1Packet Threshold To Test Up Rate
When the number of frames transmitted on the current modulation reaches this
number, the Statistics-Based Rate Control algorithm will test the upper
modulation.
The available range is between 10 and 10000.
The default value is 30.
4.2.6.5.10.3.2Packet No On Upper Rate
This option indicates the number of frames used by the Statistics-Based Rate
Control algorithm to test upper modulations.
The available range is between 1 and 3.
