This seems a different issue. When an interface is bound to the
igb_uio driver, it loses its system name ("p3p1"). DPDK uses
small integers (port ids) to identify interfaces.
OVS prefixes the portid with the "dpdk" string. This is the command
to add the NIC with port id 0 to bridge br0:
ovs-vsctl add-port br0 dpdk0 -- set Interface dpdk0 type=dpdk
Please refer to INSTALL.DPDK.md in the source distribution for
more details.
