[dpdk-users] compilation error while building mlx5 of dpdk-16.04 on Ubuntu 16.04

[Javier Blazquez]

I remember having this issue on Ubuntu 16.04 as well. It's fixed in DPDK
16.07 (there's an -rc5 version out already) but if I remember correctly I
made a local patch for DPDK 16.04 to keep going. I _think_ it was this
patch, but I'm not sure, you may want to try it:
