There is no benefit in retaining the legacy rate control module in the driver codebase. It is known to be buggy and has less than optimal performance in real-world environments compared with minstrel. The only reason that it was kept when we made the switch to minstrel as default was that it showed higher throughput numbers in a clean/ideal environment. This is no longer the case and minstrel can push ath9k to the same throughput levels. In TCP, with 3-stream cards, more than 295 Mbps can be obtained in open air, with 2-stream cards, 210 Mbps is easily reached. To test performance issues, instead of using a broken rate control module, it is better to use the fixed-rate interface provided by mac80211 anyway. The ath9k RC has not received any bug fixes in years and is just bit-rotting away - this patch removes it. Signed-off-by: Sujith Manoharan <c_manoha@qca.qualcomm.com> Signed-off-by: John W.

---help---
|
|
This option enables DFS support for initiating radiation on
|
|
ath9k. There is no way to dynamically detect if a card was DFS
|
|
certified and as such this is left as a build time option. This
|
|
option should only be enabled by system integrators that can
|
|
guarantee that all the platforms that their kernel will run on
|
|
have obtained appropriate regulatory body certification for a
|
|
respective Atheros card by using ath9k on the target shipping
|
|
platforms.
|
|
|
|
This is currently only a placeholder for future DFS support,
|
|
as DFS support requires more components that still need to be
|
|
developed. At this point enabling this option won't do anything
|
|
except increase code size.

Say N. This should only be enabled on systems undergoing

|
certification testing and evaluation in a controlled environment.
|
|
Enabling this will only enable TX99 support, all other modes of
|
|
operation will be disabled.
|
|
|
|
TX99 support enables Specific Absorption Rate (SAR) testing.
|
|
SAR is the unit of measurement for the amount of radio frequency(RF)
|
|
absorbed by the body when using a wireless device. The RF exposure
|
|
limits used are expressed in the terms of SAR, which is a measure
|
|
of the electric and magnetic field strength and power density for
|
|
transmitters operating at frequencies from 300 kHz to 100 GHz.
|
|
Regulatory bodies around the world require that wireless device
|
|
be evaluated to meet the RF exposure limits set forth in the
|
|
governmental SAR regulations.
