I think this script is a good step on the roadmap towards making DPDK build time configuration more developer friendly.
The idea of making DPDK 100 % runtime configurable and 0 % build time configurable has failed.
DPDK should be buildable by distros with a lot of features and drivers enabled, and projects using it for special use cases should have the ability to build a purpose-specific variant. Just like the kernel.
