Subject: [PATCH net-next v5 09/10] forcedeth: stats updated with a deferrable timer
Date: Tue, 15 Nov 2011 21:15:57 -0800 [thread overview]
Message-ID: <524d8d6cf90d701b63690b70d3487d794c783617.1321420513.git.david.decotigny@google.com> (raw)

Mark stats timer as deferrable: punctuality in waking the stats timer
callback doesn't matter much, as it is responsible only to avoid
integer wraparound.
We need at least 1 other timer to fire within 17s (fully loaded 1Gbps)
to avoid wrap-arounds. Desired period is still 10s.
