I built the current version of DPDK directly from dpdk.org after I
installed the current OFED Mellanox driver set:

* MLNX_OFED_LINUX-5.5-1.0.3.2-ubuntu20.04-x86_64.iso

with ./install --dpdk

I am using a Mellanox Technologies MT27710 Family [ConnectX-4 Lx] which is
Ethernet only; there is no IB mode for this NIC. This is a MT_2420110034
board. However, when I run dpdk-testpmd I see "No Verbs device matches PCI
device 0000:01:00.1, are kernel drivers loaded?"

EAL: Detected CPU lcores: 16
EAL: Detected NUMA nodes: 1
EAL: Detected static linkage of DPDK
EAL: Selected IOVA mode 'PA'
EAL: No free 2048 kB hugepages reported on node 0
EAL: VFIO support initialized
EAL: Probe PCI driver: mlx5_pci (15b3:1015) device: 0000:01:00.1 (socket 0)
mlx5_common: No Verbs device matches PCI device 0000:01:00.1, are kernel
drivers loaded?
mlx5_common: Verbs device not found: 01:00.1
mlx5_common: Failed to initialize device context.
EAL: Requested device 0000:01:00.1 cannot be used
EAL: Bus (pci) probe failed.

As far as I can see all the kernel modules are loaded:

Hi,

Based on your output, the ConnectX-4LX device is configured in LAG mode
managed via the kernel bonding scripts. In this mode, both physical
functions share a single port (mlx5_bond_0). You should only probe the
first PCI BDF - 01:00.0, not the 2nd one.

By the way, the --dpdk installation flag should not be necessary, it is an
old flag keps for Mellanox OFED builds lower than 5.x.

Regards,
Erez

Mr. Ferber, much appreciated. I knew this metal box came to me with two
mellanox NICs bonded. I used their util to unbond it, but alas it did not
do it all the way. The /etc/network/interfaces was bad. I fixed the config
and rebooted.

Voila. Success. ibv_devinfo now shows two devices. And the DPDK app runs.

Your point about bonding nudged me to double check.

*Now, on a second machine where I believe I have done everything I did on
the first machine*, running the DPDK application continues to look for the
wrong driver:

EAL: Detected CPU lcores: 16
EAL: Detected NUMA nodes: 1
EAL: Detected shared linkage of DPDK
EAL: libmlx4.so.1: cannot open shared object file: No such file or directory
EAL: FATAL: Cannot init plugins
EAL: Cannot init plugins

Somehow I fixed this on the first machine, but I cannot duplicate success
on the second machine.

Both machines report two devices; both machines show similar ifconifgs

I assume your tree assumes there's a ConnectX-3 device installed, while the
kernel driver doesnt support it for quite a while
I would suggest re-compiling while excluding mlx4 PMD support.

Thanks,
Erez

This was my error. I linked the code incorrectly. For those new to DPDK the
correct linking methodology is, using cmake, follows:

- build DPDK from dpdk.org. For example see
https://github.com/rodgarrison/reinvent then see
https://github.com/rodgarrison/reinvent/blob/main/scripts/install#L58.
While this write-up is for DPDK on AWS ENA NICs, building DPDK is the same
no matter what NIC you are using.

- configure your linking libraries with the help of pkg-config. I do it
this way
https://github.com/rodgarrison/reinvent/blob/ubuntu/CMakeLists.txt#L27 to
setup the DPDK linking command defaulting to dynamic libraries. But static
link is also possible; see else subcommand. Then, in the actual,
application use this setup, for example,
https://github.com/rodgarrison/reinvent/blob/ubuntu/integration_tests/reinvent_dpdk_udp/CMakeLists.txt#L43
