What I really want to see is the init process for OVS-DPDK that dumps the DPDK initialization.
I think you will find it at the beginning of the log that you just sent.

Kindest regards,
Raslan Darawsheh

Hello Raslan,
Thank you for your reply.

For reference the br-mlx bridge was created like this:
$ovs-vsctl add-br br-mlx -- set bridge br-mlx datapath_type=netdev

$ovs-vsctl add-port br-mlx enp59s0d1 -- set Interface enp59s0d1 type=dpdk options:dpdk-devargs=mlx4_0
ovs-vsctl: Error detected while setting up 'enp59s0d1': Error attaching device 'mlx4_0' to DPDK.  See ovs-vswitchd log for details.
ovs-vsctl: The default log directory is "/var/log/openvswitch".

In the ovs-vswitchd.log
2018-06-11T09:56:20.613Z|00185|dpdk|ERR|EAL: Unable to find a bus for the device 'mlx4_0'
