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 change the VMs' MTU from default to smaller to accommodate
the traffics, it works well.
The way I have not find 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

There are two br2 bridge on Host2. It is intentional ?
Btw, I am trying on same page but could not simplify the vm-vxlan-dpdk
working within "single" bridge case,
may be that I am yet to find right flow rules to handle vhost-user,
vxlan and dpdk ports.
I hope you are using patch port between two bridges. Would you really
need it ?
