Can someone help with this ?
I have ovs 2.7/ dpdk17.02.1
And I create a veth pair:  veth0 , veth1 
Veth1 is assigned to a namespace, and veth0 is created as an ovs port type dpdk af_packet.
I'm failing  to set its MTU  to jumbo during creation  -[default MTU is OK]
I get these error msgs when trying to set jumbo MTU :
ovs-vswitchd[1930]: ovs|00614|netdev_dpdk|WARN|Error attaching device 'eth_af_packet0,iface=veth0' to DPDK
ovs-vswitchd[1930]: ovs|00615|netdev|WARN|veth0: could not set configuration (Invalid argument)
ovs-vswitchd[1930]: ovs|00616|netdev|WARN|veth0: arguments provided to device that is not configurable
Best Regards
