Hi, folks
Netfilter added a shifted port range mapping function in Linux kernel 4.19, it
looks like this:
iptables -t nat -A zone_wan_prerouting -p tcp -m tcp --dport 5000:5100 -j DNAT
--to-destination '192.168.1.2:2000-2100/5000'
5000-51000 is mapped to 2000-2100

Hi, folks
Recently we found some weird issues, ovs-vswitchd will crash occasionally when

host, or openflows in br-int can’t work as

Hi, folks
I’m changing Openstack Neutron to use openflow-based pipeline to implement

Out of curious, I remember OVN doesn't support OVS DPDK, I believe OVN also
does IPv6 ND by openflow, is it acceptable to use slow path to handle IPv6 ND
for OVS kernel datapath?

Hi, folks
I noticed ping from local IP to remote IP of VXLAN port can’t work immediately
after OVS DPDK is started and VXLAN port is created, sometimes it needs to wait
for more than 1 minute, I found ARP request triggered by ping and ARP request
sent by ovs itself can’t be responded

destination MAC of these packets are fa:16:3e:49:26:51, not broadcast MAC, VM
interface is not in promisc mode.
Look forward to getting your guide, is this default behavior of OVS? Can you
explain this "NORMAL" action?

Flavio, this is an openstack environment, all the flows are added by neutron,
NORMAL action is default flow before neutron adds any flow, this is ovs default

Hi, all
We find ovs has serious performance issue, we only launch one VM in one
compute, and do iperf small udp pps performance test between these two VMs, we
can see about 18 pps (packets per second, -l 16), but
1) if we add 100 veth ports in br-int bridge, respectively, then the pps

William, use the below option for your tap0

This seems to be related to netdev-afxdp's batch size bigger than kernel's xdp
batch size.
I created a patch to fix it.

Could anyone take a look at this patch
