Subject: [PATCH 1/3] ath5k: Use EWMA factor of 1024 instead of 1000
Date: Thu, 02 Dec 2010 19:12:31 +0900 [thread overview]
Message-ID: <20101202101231.22988.33396.stgit@localhost6.localdomain6> (raw)
This prepares the only place which uses the EWMA library so far for the
performance improved implementation coming up, which requires factor and
weight to be a power of two.
