[dpdk-users] Compile DPDK 17.11 with Mellanox NIC support

I believe you are missing the --upstream-libs from OFED installation:

Try it as following:
./mlnxofedinstall --skip-distro-check --dpdk --add-kernel-support --upstream-libs /etc/init.d/openibd restart 

Then rebuild your DPDK.

Kindest regards,
Raslan Darawsheh

I met the same problem.  My DPDK build environment is "CentOS7.0 + kernel 3.10.0-229.el7.x86_64".
I have download the OFED 4.2 and use the following command to install:
./mlnxofedinstall --skip-distro-check --dpdk --add-kernel-support /etc/init.d/openibd restart However, I still met error while I am compiling DPDK-17.11. The error information is :

In file included from /home/wangyong/dpdk-17.11/drivers/net/mlx4/mlx4.c:71:0:
/home/wangyong/dpdk-17.11/drivers/net/mlx4/mlx4_rxtx.h:44:31: fatal error: infiniband/mlx4dv.h: No such file or directory  #include <infiniband/mlx4dv.h>
compilation terminated.
make[6]: *** [mlx4.o] Error 1
make[5]: *** [mlx4] Error 2
make[4]: *** [net] Error 2
make[3]: *** [drivers] Error 2
make[2]: *** [all] Error 2
make[1]: *** [pre_install] Error 2
make: *** [install] Error 2

I checked the "/usr/include/infiniband" directory and I couldn't find the mlx4dv.h file.
Are there any other configurations or steps required? Or the kernel version of linux can't be 3.10 ?

Thanks for the prompt reply and guidance!
My OFED version was 4.1, that's why I was unable to build DPDK 17.11.
With OFED 4.2 everything works on my kernel (v4.4)!

I have one more question: What is the suggested OFED version in order to have a fully featured NIC with all the DPDK classification/offloading capabilities?
My NICs are 100G ConnectX-4 (dual and single port).

Best regards,
