Hi,

FYI, your patch has been queued to stable release 16.07.1

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable
yet. It will be pushed if I get no objections before this Friday.
So please shutout if anyone has objections.

Thanks.

Subject: [PATCH] timer: fix lag delay

[ upstream commit 0778cfe8642a08934724cf34a4bb2f1fba91cc88 ]

For periodic timers, if the lag gets introduced, the current code added additional delay when the next peridoc timer was initialized by not taking into account the delay added, with this fix the code would start the next occurrence of timer keeping in account the lag added. Corrected the behavior.

Fixes: 9b15ba89 ("timer: use a skip list")
