supported by what?
* by a statically linked app
* by a DPDK he has downloaded and built
* by a DPDK provided as shared library by its Linux vendor
In the first 2 cases he knows where the files are.
In the Linux distribution case, there can be a default directory set
by the Linux vendor for the script looking at the infos. Only the Linux
vendor knows where the PMDs files are.

You mean "which DPDK packages"?
Are some informations showed when doing "packager search dpdk"?
or "packager show dpdk-driverX"?
Do you want to show the PCI ids in the description of the packages?

> - user wants to list all supported hardware before going shopping

Why doing shopping? For a DPDK usage or for a specific application?
The application should mentions the supported hardware.
For more general DPDK information, there is this this page:
	http://dpdk.org/doc/nics
But it may be not enough accurate for some PCI id exceptions.
For more details, he must use a listing tool.
