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.
