As following topology, two VMs communicate via VXLAN tunnel.
TCP pkts may be droped for exceeding the MTU of host DPDK port in br2.
Now I can decrease VMs' MTU to accommodate the traffics, it works well.
The way I have not found to change MTU of DPDK phy port, is there a
blueprint for supporting this by ovs, like "ovs-appctl
netdev-dpdk/set-xxx" or another way?
Host1 | Host2
(l-ip)- L3 -(r-ip)
----- ----- ----- | ----- ----- ----- -----
|VM1| --|br1|Vxlan --|br2|DPDK---DPDK|br2|--Vxlan|br2|--|br1|--|VM2|
----- ----- ----- | ----- ----- ----- -----
I forward this to dev mail-list, anyone who can response me? Thanks.
