+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.
