I didn't see the issue that this patch fixes initially. However, if I make the
below change, I can see the error during the test.
Change:

Which causes a fail:
7. system-dpdk.at:254: FAILED (system-dpdk.at:280)
Applying this patch while keeping the above diff to generate the flow limit
error results in the test passing. I can see the "reached the dynamic limit"
warning in the ovs-vswitchd.log but it doesn't cause a test failure.
Finding the value of "13500" as a flow-limit took some experimentation and
would probably vary based on platform.
With that, and looking at the .at changes, LGTM.
