[dpdk-users] Enable MLX5 driver v20.11

[Raslan Darawsheh]

Starting OFED 5.1 it stopped the support for MLX4 pmd
And seems that you have some libmlx4 under your local lib dir,
In the meanwhile what you can do when doing ninja is to disable mxl4 compilation:

meson build -D disable_driver=net/mlx4; ninja -C build

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?

Hi Gerry,

Starting V20.11 the build system was switched to use meson only,
And if you have necessary packages for MLX5 (a.k. rdma-core) it will be built automatically.

As for your question if you still don't need to bind mlx5 driver that's true, its still valid.
