Problem with MBUF pool allocation

[Marco Varlese <marco.varlese@suse.com>]

Hi,
I'm seeing an error reported by the DPDK EAL when allocating the MBUF pools.

The error is:
"MBUF: error setting mempool handler"

I have a multi-node NUMA system and I get the exact same error when trying to
allocate the memory from the different nodes. 

The bootstrap parameters I use to reserve huge-pages are:
"default_hugepagesz=1G hugepagesz=1G hugepages=32"

If I check the available huge-pages in my systems they look Ok (see below).
