[dpdk-users] EAL: PCI device 0000:04:00.0 on NUMA socket -1

[Vincent Li]

Hi

I am using Intel 82599 on Dell PowerEdge R710 which should support
NUMA node, the box is running ubuntu 14.01.1 LTS, I am wondering why I
get NUMA socket -1. in BIOS, the memory "Node Interleaving" is
disabled by default, any clue?
