From: Peter Oh Date: Tue, 31 Mar 2015 23:44:43 +0000 (-0700) Subject: ath: lower JP W53 band DFS detection threshold around 30% X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=26bea13a65654b21b224a47daf02827c79302f2e;p=linux-beck.git ath: lower JP W53 band DFS detection threshold around 30% Japan's W53 band requires 50% data traffic during its DFS test, but WLAN baseband used by ath9k and ath10k is not able to achieve current threshold rate, 50%, under the data traffic rate. In other words, HW occasionally fails detecting radar pulses, so that SW cannot get enough radar reports to achieve the rate.
