Some partial offloading test cases are failing inconsistently. The root
cause is that dummy netdev is assigned with "linux_tc" offloading API.
dpif-netdev - partial hw offload - dummy
dpif-netdev - partial hw offload - dummy-pmd
dpif-netdev - partial hw offload with packet modifications - dummy

In the same environment, but I used tap but not veth, retr number is 0 for
the case without this patch (of course, I applied Flavio's tap enable patch)
vagrant@ubuntu1804:~$ sudo ./run-iperf3.sh
Connecting to host 10.15.1.3, port 5201

This is the result in my VM for the case without this patch. Retr number is
really very very high, this is super abnormal. Physical machine has same
phenomenon.

William, I tested it in VM because I doesn't have physical machine with new
kernel, the number is similar, mine is about 2 Gbps, can you show me your
iperf output for the case without this patch, I saw a very strange
phenomenon, with this patch, retransmit is almost 0, but without this patch,

Read/write concurrency of pvector library is implemented by a temp vector
and RCU protection. Considering performance reason, insertion does not
follow this scheme.
In insertion function, a thread fence ensures size incrementation is done
after new entry is stored. But there is no barrier in the it

Currently ovs-bugtool does not work due to Python2 deprecated.
When moving to Python3, a couple of things are broken in ovs-bugtool,
ex: import libraries issues such as StringIO and commands.
Also there are some bytes to string convertion in this patch
because in Python3,strings are now always Unic

This patch reverts the below patches which added lflow expr caching
supported and follow up patches which fixed few issues.
With the present lflow expr caching we still have issues with logical
flows referencing port groups/address sets. If a port group/address set

I have worked around it. Looking at the source I can guarantee that it is a
work-around and not a 100% fix, but it has survived an overnight loop run on a
6 core/12 thread 3.5 GHz Ryzen.
The root cause is that instead of using a proper packet oriented interface (f.e
