[dpdk-users] Enable MLX5 driver v20.11

[Gerry Wan]

Thanks,
I updated my MLNX_OFED to 5.1-2.5.8.0, which was tested against for this
DPDK release.
To install, I ran ./mlnxofedinstall --dpdk --upstream-libs --with-mft
--with-kernel-mft
then /etc/init.d/openibd restart
Now, ninja install gives me ../drivers/net/mlx4/mlx4_glue.h:16:10: fatal
error: infiniband/mlx4dv.h: No such file or directory

What other steps am I missing?
