In my opnion, no application should have to make special case setup
for each device type. Having to have a table that lists all the parameters
for each device name is not supportable or scaleable.

The DPDK started out as "lets do benchmarks fast" but as a production
toolkit it needs to stop having this kind of thing.

The message shows up to the end-user, who thinks it is a driver bug.
The "us" is now real customers not DPDK developers.
