This is causing testpmd fail for the case all cores from socket 1 and added a
virtual device which will try to allocate memory from socket 0.
$ testpmd -l<cores from socket 1> --vdev net_pcap0,iface=lo -- -i

Failed to setup RX queue:No mempool allocation on the socket 0
EAL: Error - exiting with code: 1
Cause: Start ports failed
