thanks for your help.
It work well. I merge the code of V2 in

Hi,
 
The ‘mtu’ field of the Interface table is a read-only field in OVSDB, hence it 
can’t be set via a call to ovs-vsctl.
 
Work is currently underway to provide a mechanism to modify netdev parameters 
dynamically at runtime; such parameters could include # RX queues, MTU, etc. 
See here: http://openvswitch.org/pipermail/dev/2016-April/069835.html 
 
In the meantime, if you’d like to play around with Jumbo frames and OVS-DPDK, 
you can use this patchset: 
http://openvswitch.org/pipermail/dev/2016-February/066405.html. 
Note, however, that this patchset is superseded by the aforementioned ‘dynamic 
netdev reconfigure’ series, and will not form part of the OVS codebase.
 
Thanks,
Mark

I have test with the command: ovs-vsctl set interface *** mtu=***.
but the mtu of the interface always be 1500, why?
 
or there are any other methods to set the mtu of dpdk-type interface?
 
best regards
