The imissed port statistic counts packets that were dropped by the
device Rx queues.
In mlx5, the imissed counter summarizes 2 counters:
- packets dropped by the SW queue handling counted by SW.
- packets dropped by the HW queues due to "out of buffer" events
detected when no SW buffer is available for the incoming
packets.
There is HW counter object that should be created per device, and all
the Rx queues should be assigned to this counter in configuration time.
This part was missed when the Rx queues were created by DevX what
remained the "out of buffer" counter clean forever in this case.
Add 2 options to assign the DevX Rx queues to queue counter:
- Create queue counter per device by DevX and assign all the
queues to it.
- Query the kernel counter and assign all the queues to it.
Use the first option by default and if it is failed, fallback to the
second option.
