-    [6] OPEN Regression in CSIT, one specific test showing too small stdev
-    to be considered noise. Tentatively marking also other ipsec anomalies
-    with this, although their stdev are high enough to be explained
-    as maybe just noise. [CSIT-1742]
+    [6] DONE Apparent regression in CSIT is caused by VPP renaming
+    the most performant IPsec plugin, thus the current CSIT version used with
+    the previous VPP version measures the less performant VPP IPsec plugin.

     [7] POSTPONED Possible anomaly, but stdev of results is high.
-    Currently, the performance differences are considered to probably be just noise.

-    [8] DONE Regressions in some tests with VPP in VM.
-    Tests using l2xcbase as vswitch have small enough stdev for bisect.
-    The switch to clang-9 compiler, Gerrit 26744, has been identified as the cause.

-    [9] OPEN Progression in ip6 scale tests. Multiple candidate changes may have
-    affect code efficiency, but they have also caused the tests to fail
-    for a period of time. [CSIT-1735]
