[dpdk-dev] Fwd: [PATCH] PPC: Fix NUMA node numbering on IBM POWER8 LE machine

[Chao Zhu]

Actually, without this change, DPDK can't work properly on PPC64 little 
endian platform. It'll report "EAL: Not enough memory available! 
Requested: xxxMB, available: xxxMB" such kind of error. But for users, 
they don't know that changing the value of CONFIG_RTE_MAX_NUMA_NODES can 
fix this.  That why I invoke this patch.
