Changes in |csit-release|
-------------------------
-No code changes apart from bug fixes.
+#. DPDK PERFORMANCE TESTS
-Performance Changes
--------------------
+ - Fixed DPDK compilation on ARM systems.
-Relative performance changes in measured packet throughput in |csit-release|
-are calculated against the results from |csit-release-1|
-report. Listed mean and standard deviation values are computed based on
-a series of the same tests executed against respective VPP releases to
-verify test results repeatability, with percentage change calculated for
-mean values. Note that the standard deviation is quite high for a small
-number of packet throughput tests, what indicates poor test results
-repeatability and makes the relative change of mean throughput value not
-fully representative for these tests. The root causes behind poor
-results repeatability vary between the test cases.
+#. DPDK RELEASE VERSION CHANGE
-NDR Changes
