Commit Message

Neil Horman May 16, 2016, 8:41 p.m. UTC 
Modify the PMD_REGISTER_DRIVER macro, bifurcating it into two
(PMD_REGISTER_DRIVER_PDEV and PMD_REGISTER_DRIVER_VDEV.  Both of these do the
same thing the origional macro did, but both add the definition of a string
variable that informs interested parties of the name of the pmd, and the former
also defines an second string that holds the symbol name of the pci table that
is registered by this pmd.

pmdinfo uses this information to extract hardware support from an object file
and create a json string to make hardware support info discoverable later.
