From: Yan-Hsuan Chuang Date: Mon, 3 Apr 2017 18:41:40 +0000 (-0500) Subject: rtlwifi: btcoex: 23b 2ant: finer bt power adjustment X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=44e9a5340e6859a2a00cc470a8acfcbcaf64050a;p=openwrt%2Fstaging%2Fblogic.git rtlwifi: btcoex: 23b 2ant: finer bt power adjustment The bt can specify a power level to decrease. Rather than decreasing by a fixed value (usually 2), this change makes the driver fit to the environment more quickly.
