From 6044682b83a08618a4d8f6791503e0cec5b9fbe5 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Tomislav=20Po=C5=BEega?= <pozega.tomislav@gmail.com> Date: Wed, 23 Aug 2017 19:10:21 +0200 Subject: [PATCH] mac80211: rt2x00: write registers required for reducing power consumption MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Write registers required for reducing power consumption like the vendor driver does when ADJUST_POWER_CONSUMPTION_SUPPORT is set. This helps devices to sync at better TX/RX rates and improves overall performance.
