Executed testpmd application and encountered no free page issues

[Paul Tsvika]

Hi,

I have one board with two 10G etherent on it. ( and two 1G ethernet as well
)

Below is my working environment:

OS: Ubuntu 16.04
10G Ethernet controller: X552/X557-AT 10GBASE-T
Ethernet driver: ixgbe - 4.2.1-k
dpdk version: 17.02.1

In order to avoid doing configuration incorrectly, i run the dpdk-setup.sh
in the directory usertools.

Is there anything I might not do right ?

Your reply is appreciated.
