We would like to introduce a HW offloading solution for scenario that one
packet goes through DPDK OVS pipeline multiple times with recircle action. We
call it merged-single-table HW offloading.
The standard use case is to support conntrack with HW offloading. Example, the

Hi,
I also found that if once theres are lots of flows, the memory (RSS) usage of
OVS process would be quite high, 2~3GB. Even then the flows disappear later,
the memory still keeps.
I am not sure how many people notices this, but if indeed OVS has such defect,

Hi,
I am testing below scenario, and I think there is some issue on TCP conntrack
sequence number filter.
Scenario:
VM1->Host1-Host2-->VM2
There is SCP file copy below VM1 and VM2, and we configured conntrack. During
the scp, I restart the openvswitch service (process stop and
can be done at end host
stack).
I am open to the decision. So if you think your patch is more suitable, I can
be the co-author.

Ovs and kernel stack would add frag_queue to same netns_frags list.
As result, ovs and kernel may access the fraq_queue without correct
lock. Also the struct ipq may be different on kernel(older than 4.3),
which leads to invalid pointer access.
The fix creates specific netns_frags for ovs.
