Subject: [PATCH] mac80211: round station cleanup timer
Date: Mon, 17 Dec 2007 15:07:43 +0100 [thread overview]
Message-ID: <1197900463.4885.43.camel@johannes.berg> (raw)
The station cleanup timer runs every ten seconds, the exact
timing is not relevant at all so it can well run together with
other things to save power.
