-------------------
-* eal: DPDK runtime configuration file (located at
- ``/var/run/.<prefix>_config``) will be moved. The new path will be as follows:
-
- - if DPDK is running as root, path will be set to
- ``/var/run/dpdk/<prefix>/config``
- - if DPDK is not running as root and $XDG_RUNTIME_DIR is set, path will be set
- to ``$XDG_RUNTIME_DIR/dpdk/<prefix>/config``
- - if DPDK is not running as root and $XDG_RUNTIME_DIR is not set, path will be
- set to ``/tmp/dpdk/<prefix>/config``

device and device drivers. Device declaration will be made coherent with the
