Subject: [PATCH 1/7] wl12xx: set the ELP entry delay to the FW dyn-ps timeout
Date: Tue, 28 Feb 2012 00:41:28 +0200	[thread overview]
Message-ID: <1330382494-31148-1-git-send-email-arik@wizery.com> (raw)

With PSM handled in FW, the checks in wl1271_elp_work() are always true.
Thus during active traffic we constantly enter and exit ELP (many times
per second). As each ELP exit takes ~10ms, this can have an adverse
effect on throughput and interactivity.
Set the ELP timeout to the dyn-ps timeout. This period is longer and
avoids the above problem. It also makes sense to stay out of ELP while
we are awake on the network, to minimize delays in Tx/Rx. The same thing
was done by the mac80211 dynamic-ps mechanism before the FW DPS changes.
