Sorry, this patch fell into the cracks.

I agree that this is not part of the ABI policy.
This version only indicates something internal.

But what I am proposing here is just to remove this special case.
What is the point of exposing a special version, while the net drivers
are the only one depending on those glue libs?
Do you expect separate packaging for the net driver and its associated glue lib?

This special version also makes it impossible to install two versions
of dpdk if those versions of dpdk need the same glue version.

I still think it is better to align to the version of dpdk, though the
commitlog needs some work.
