[dpdk-dev] [PATCH] eal: fix plugindir processing to be filesystem agnostic

[Panu Matilainen]

Not all filesystems supply struct dirent d_type field, in which case
everything in the specified directory would go ignored. One such
filesystem being XFS which RHEL 7 defaults to... stat() the entries
instead.

Fixes: 9f8eb1d9ca0f ("eal: support driver loading from directory")
