Hi, Thomas

Historically mlx5 created Queues and other HW objects with Verbs.
Now we are migrating ("switched") to DevX - queues are being created with DevX
calls.
If there is no E-Switch - the new DevX approach is engaged,
for E-Switch configurations we still use Verbs.

When switching to the Devx interface, the kernel driver behavior may
be different from using Verbs. The Tx loopback cannot work properly
even if the Tx and Rx queues are configured with loopback attribute.
To support self loopback for Tx, a Verbs dummy queue pair needs to
be created to trigger the
