The generator is deprecated and it will be replaced with pktgen and it
has become a maintenance burden now when the API is changing so rapidly.

I think I agree, it has been hard to have the bandwidth to progress the
generator and we have started to use DPDK-pktgen for real tests such as
L2FWD

With the maturing of the ODP APIs for 1.0 I hope implementing a pktgen
based tool will be easier than when the generator was created for 0.1 as a
way to get any packets in and out.

The only issue I see is a need to drive ODP without a pktio interface that
directly put data into a queue. I assume pktgen will need a loopback
interface if no real interface is involved - is that an issue ?
