[dpdk-dev,PATCHv3,3/5] eal: Add an export symbol to expose the autoload path to external tools
Commit Message
Export a symbol containing the string:
DPDK_PLUGIN_PATH="$(CONFIG_RTE_EAL_PMD_PATH)"
Where the latter half of the string is set at build time to a location from
which autoloaded DSO's will be found. This string is used by pmdinfo in
'plugin' mode, whereby a user can specify a dpdk installation directory (or
static binary), and scan the associated path (if found) for pmd DSO's and report
on their hardware support.
