HI,

I am Praveen,

I am trying a specific test scenario using ovs-dpdk.

Test set up
-------------------

from the traffgen vlan packets are coming to dpdk interface its stripped
using ovs command.
and sending to a vxlan interface which is comnnected in theo other dpdk
interface and send back to traffgen.

i have done the vxlan set up similar to the sample test case.

https://github.com/openvswitch/ovs/blob/master/README-native-tunneling.md

the issue is that from the sumpflows i can see that packets are send to
vxlan but it is not going to the other bridge.

the same scenario is working without dpdk.

I am using openvswitch-2.4.0.

Linux (without dpdk)
---------------------------------

ovs-vsctl add-br br0
ovs-vsctl add-port br0 eth0
ovs-vsctl add-port br0 vxlan0 -- set interface vxlan0 type=vxlan
options:remote_ip=10.200.0.6
ovs-ofctl add-flow br0
dl_vlan=1,dl_dst=02:11:22:44:55:22,actions=strip_vlan,output:2

ovs-vsctl add-br br1
ovs-vsctl add-port br1 eth1

 ip a a 10.200.0.5/24 dev br1
arp -s 10.200.0.6 02:11:22:44:55:11 -i eth2

and from the traffgen i am sending traffic with dst mac 02:11:22:44:55:22
and vlan id 1.
it is correctly working.

ovs-dpdk
------------------

started ovs-dpdk ::
ovs-vswitchd --dpdk -c 0x1 -n 4 -- unix:$DB_SOCK --pidfile --detach

ovs-vsctl add-br br0 -- set bridge br0 datapath_type=netdev
ovs-vsctl add-port br0 dpdk0 -- set Interface dpdk0 type=dpdk

ovs-vsctl add-br br1 -- set bridge br1 datapath_type=netdev
ovs-vsctl add-port br1 dpdk1 -- set Interface dpdk1 type=dpdk

ovs-vsctl add-port br0 vxlan0 -- set interface vxlan0 type=vxlan
options:remote_ip=10.200.0.6
ovs-ofctl add-flow br0
dl_vlan=1,dl_dst=02:11:22:44:55:22,actions=strip_vlan,output:2

 ip a a 10.200.0.5/24 dev br1
arp -s 10.200.0.6 02:11:22:44:55:11 -i eth2


here i have started the ovs-dpddk and do the same set up
but packets are not seen in bridge1 (br1) and in traffgen.

is there any specif configuration i need to do in ovs-dpdk
could it be because of the arp?
Is there a way to set static arp to the ovs-dpdk?

Could you help in identifying the problem?

Thanking you in advance
Praveen
