Rather than having a new private API for this, would a device arg (devarg)
passed on the commandline be a better choice? Private APIs are not really
nice in DPDK, and for this feature I can't see it being something that
needs enabling/disabling at runtime by apps. Just having it as a device
setting, set at init should probably work.
