CACHE_LINE_SIZE is a macro defined in machine/param.h in FreeBSD and conflicts with DPDK macro version. Adding RTE_ prefix to avoid conflicts. CACHE_LINE_MASK and CACHE_LINE_ROUNDUP are also prefixed. Signed-off-by: Sergio Gonzalez Monroy <sergio.gonzalez.monroy@intel.com> [Thomas: updated on HEAD, including PPC]
