-Subject: [PATCH] ath10k: enable adaptive CCA
-
-European Union has made it mandatory that all devices working in 2.4 GHz
-has to adhere to the ETSI specification (ETSI EN 300 328 V1.9.1)
-beginnig this year. The standard basically speaks about interferences
-in 2.4Ghz band.
-For example, when 802.11 device detects interference, TX must be stopped
-as long as interference is present.
-
-Adaptive CCA is a feature, when enabled the device learns from the
-environment and configures CCA levels adaptively. This will improve
-detecting interferences and the device can stop trasmissions till the
-interference is present eventually leading to good performances in
-varying interference conditions.
-
-The patch includes code for enabling adaptive CCA for 10.2.4 firmware on
-QCA988X.
