[dpdk-dev] ConnectX4 100GbE - Compilation problem

[george.dit@gmail.com]

Hi,

I have a single port Mellanox ConnectX 4 100GbE NIC and I want to test its
Rx/Tx capabilites  using DPDK.
My system runs a Linux kernel 4.4 compiled from sources.

I found the PMD driver for this NIC as provided by Mellanox here
<http://www.mellanox.com/page/products_dyn?product_family=209&mtag=pmd_for_dpdk>
.
Following this
<http://www.mellanox.com/related-docs/prod_software/MLNX_DPDK_Quick_Start_Guide_v2.2_2.7.pdf>
guideline, I put my NIC in Ethernet mode, configured the 3 options
regarding mlx5 in the config/common_linuxapp file and applied 'make install
T=x86_64-native-linuxapp-gcc'.

Then, I stumbled upon a compilation problem in the mlx4 module.
The compiler's output is as follows:

== Build drivers/net/mlx4
  CC mlx4.o

Iwould appreciate any suggestions and guidance.
