** Description changed:
+
+ == SRU Justification ==
+ 6Wind is requesting these three patches. The patches fix a bug that prevents
a user
+ from following an interface that moves to another netns.
+
+ These commits are also needed in Xenial. However, they will be sent in
+ a separate SRU request due to additional prereq commits being needed for
+ Xenial.
+
+ == Fixes ==
+ b2d3bcfa26a7 ("net: core: Expose number of link up/down transitions")
+ c36ac8e23073 ("dev: always advertise the new nsid when the netns iface
changes")
+ 38e01b30563a ("dev: advertise the new ifindex when the netns iface changes")
+
+ == Regression Potential ==
+ Medium due to three patches needed and the changes to core networking.
+
+ == Test Case ==
+ A test kernel was built with these patches and tested by the original bug
reporter.
+ The bug reporter states the test kernel resolved the bug.
+
+
+
+
+
The following upstream patches are missing (v4.16):
6621dd29eb9b ("dev: advertise the new nsid when the netns iface changes")
c36ac8e23073 ("dev: always advertise the new nsid when the netns iface
changes")
