Subject: [PATCH] cfg80211: lower dynamic PS timeout to 100ms
Date: Fri, 31 Jul 2009 11:18:13 +0200	[thread overview]
Message-ID: <1249031893.29587.63.camel@johannes.local> (raw)

The default of 500ms is pretty high, and leads
to the device being awake at least 50% of the
time under such light traffic conditions as a
simple 1 second interval ping. Reduce to just
100ms -- it should have a similar effect while
providing a better sleep time.
