Hi, Detailed Description :
I am trying to test VXLAN with OVS bridge with L2 driver. With OVS release version [2.4.0] package VXLAN udp port configuration is not notified to L2 driver via ndo_add_vxlan_port interface. Due to this hardware is not able to do offload of features [like checksum etc.], Hence TCP/IP traffic with encapsulated offload enabled on NIC is not working. How to reproduce: With L2 driver loaded - NIC interface eth0 [IP: 192.168.110.10] on the system 1) Installed OVS v 2.4.0 on the system 2) Created OVS bridge "ovs-vx" using "ovs-vsctl add-br ovs-vx" 3) ovs-vsctl add-port ovs-vx vxlan0 -- set interface vxlan0 type=vxlan options:remote_ip=192.168.110.20 options:key=100 options:dst_port=4789 - Here with this step VXLAN UDP port 4789 is not being notified to L2 interface eth0. 4) Configured IP on "ovs-vx" internal port [IP: 192.168.100.10] 5) Tried to ping remote "ovs-vx" internal port - ping 192.168.100.20 [Works fine] 6) Try running TCP/IP traffic between "ovs-vx" internal ports - it doesn't work with encapsulated offload enabled on NIC(eth0) interface. Expected result: VXLAN UDP port configuration must be notified to L2 interface [to eth0]. Addition Note: With OVS [v2.3.2] VXLAN udp port configuration was getting notified to L2 driver and there TCP/IP traffic with encapsulated offload worked fine. Please let me know if any more information is required.
