From 0ce3bcfc84900a64347b0fe1140229bd81314008 Mon Sep 17 00:00:00 2001 From: Mohammed Shafi Shajakhan Date: Tue, 7 Dec 2010 21:14:15 +0530 Subject: [PATCH] ath9k: Parse DTIM period from mac80211 With the current save power save implementation we assume a dtim period of 1.This value is assigned based on a sanity check in the driver eventhough we had not parsed it from mac80211.This patch obtains the actual DTIM period from AP by parsing it from mac80211.Yet for handling multicast traffic we may still have it as fixed rather than parsing it from mac80211 .This does not breaks power save or anything as the sleep duration is currently fixed in the driver.This patch may serve to improve power save in the future by using dtim period for sleep duration and using correct dtim period adhoc mode.
