Hi,
We are running testpmd with 150MB(2M huge pages) with OVS DPDK (17.0.2) but
ran into issues as pmd interfaces are shown as link down.
./testpmd -c 0x3 -n 4 *--socket-mem 150* --no-pci

Same thing works fine with 1024m ( 1G hugepage). Our mbuf doesn't change,
it is around 35m in both cases.

Is there some argument missing in testpmd, as in the non working case queue
is getting disabled.
