[Christian Ehrhardt ]

[Impact]
This release sports mostly bug-fixes and we would like to make sure all of our
supported customers have access to these improvements. Among other things this
also fixes a test issue with newer DPDK which will unblock providing the backport
of that stable release.

The update contains the following package updates:

   * openvswitch 3.3.1

For more details see:

   * https://www.openvswitch.org/releases/NEWS-3.3.1.txt
   * https://github.com/openvswitch/ovs/compare/v3.3.0...v3.3.1

It will include [1] which can thereby be dropped from the delta.

[Test Case]

The following SRU process was followed:

https://wiki.ubuntu.com/OpenStack/StableReleaseUpdates

In order to avoid regression of existing consumers, the OpenStack team will
run their continuous integration test against the packages that are in
-proposed. A successful run of all available tests will be required before the
proposed packages can be let into -updates.

The OpenStack team will be in charge of attaching the output summary of the
executed tests. The OpenStack team members will not mark ‘verification-done’ until
this has happened.

[Regression Potential]
In order to mitigate the regression potential, the results of the
aforementioned tests are attached to this bug.
