I don't know any DPDK app dynamically linked with a PMD (with DT_NEEDED).
However it is a good idea to handle this case.
But relying on the name assumption "librte_pmd" is really weak.

I think we must prefix the tool name with dpdk.
What about dpdk-objinfo or dpdk-pmdinfo?

Should it be possible to implement pmdinfogen with this
Python library?
I'll probably comment on the pmdinfo script details later.
Just knowing you did a tool is enough to assert that it is a good step :)
Thanks
