Build Update for ovsrobot/ovs
-------------------------------------

Build: #671
Status: Passed

Duration: 1 hr, 8 mins, and 22 secs
Commit: c6b4786 (series_97922)
Author: Ilya Maximets
Message: dpif-netdev-perf: Fix millisecond stats precision with slower TSC.

Unlike x86 where TSC frequency usually matches with CPU frequency,
another architectures could have much slower TSCs.
For example, it's common for Arm SoCs to have 100 MHz TSC by default.
In this case perf module will check for end of current millisecond
each 10K cycles, i.e 10 times per millisecond. This could be not
enough to collect precise statistics.
Fix that by taking current TSC frequency into account instead of
hardcoding the number of cycles.
