New OVS-DPDK testsuite, which can be launched via `make check-dpdk`,
tests OVS using a DPDK datapath. The testsuite contains already
initial tests:
 1. EAL init
 2. Add standard DPDK PHY port
 3. Add vhost-user-client port

Hi Marcin,

Thanks for the v2 of this patch and thank you for addressing my comments. I have tested again with the latest master and can confirm that this works like in the v1 with ixgbe and i40e devices. I can also confirm that the 3rd test (Add vhost-user-client port) is no longer skipped when no devices are bound to DPDK.
The patch has passed all my tests and passes checkpatch.

Hi Marcin,

Thanks for working on this, a few comments inline below.

These tests will require elevated privileges (root or sudo) on systems to be run, otherwise they will fail as memory will not be allocated etc. by ovs-dpdk.

I'd like to see this called out explicitly in the documentation along with a short explanation (it's obvious to those familiar with DPDK but we must assume a user may not be, also existing ovs unit test can be run without these privileges so someone might work from that assumption).

In testing I also see the following error although it does not stop the test from running.

set /bin/sh './tests/system-dpdk-testsuite' -C tests  AUTOTEST_PATH='utilities:vswitchd:ovsdb:vtep:tests::ovn/controller-vtep:ovn/northd:ovn/utilities:ovn/controller'  -j1; \
"$@" || (test X'' = Xyes && "$@" --recheck)

Have you tested above on a single socket system? I guess the requirements assumes a dual socket server because a pci device may be attached to either socket but would this fail if there was only 1 socket?

Thanks

Such information is covered in a parent paragraphs (one level above and two 
levels above). However, I will add such information to the documentation explicitly.

I also see such error when running any other unit tests of OVS. 
So it's not related with my changes.

+To test :doc:`/intro/install/dpdk` (i.e., the build was configured with
+``--with-dpdk``,the ``DPDK`` is installed), run the testsuite and generate
+a report by using the ``check-dpdk`` target::
+
+    $ make check-dpdk
+
+To see a list of all the available tests, run::
+
+    $ make check-dpdk TESTSUITEFLAGS=--list
+
+These tests require a `DPDK supported NIC`_ and proper DPDK variables
+(``DPDK_DIR`` and ``DPDK_BUILD``). Moreover you need to load the required
+modules and bind the NIC to the DPDK-compatible driver.
