  The DPAA bus driver is defining some macros without prefix.
So it can conflict with other libraries like libbsd:

	drivers/bus/dpaa/include/compat.h:53:
		error: "__packed" redefined
	/usr/include/bsd/sys/cdefs.h:120:
		note: this is the location of the previous definition

Fixes: 39f373cf015a ("bus/dpaa: add compatibility and helper macros")
Cc: stable@dpdk.org
Cc: geoff.thorpe@nxp.com
Cc: hemant.agrawal@nxp.com
Cc: shreyansh.jain@nxp.com

A similar patch was also issued by Jerin a few weeks back:
http://patches.dpdk.org/patch/40597/

There may be conflict while merging.

Whether you take that, or this (preferred):
