I've been playing with this a little and I've come up with an
incremental with these changes:
* Detaching fails if port_id is in use by netdev
* I suggested before to process the arguments in reconfigure(). I
realize now that it's probably better to populate 'port_id' in
set_config() and start th
'dpdk' ports no longer have naming restrictions. Now, instead of
specifying the dpdk port ID as part of the name, the PCI address of the
device must be specified via the 'dpdk-devargs' option. eg.
ovs-vsctl add-port br0 my-port
ovs-vsctl set Interface my-port type=dpdk
ovs-vsctl set Interface my-p
