[dpdk-dev] [PATCH v3 11/12] eal: make the global configuration private

[David Marchand <david.marchand@redhat.com>]

Now that all elements of the rte_config structure have (deinlined)
accessors, we can hide it.

Signed-off-by: David Marchand <david.marchand@redhat.com>
Acked-by: Thomas Monjalon <thomas@monjalon.net>
