This commit adds dlb v2.5 probe support, and updates
parameter parsing.

The dlb v2.5 device differs from dlb v2, in that the
number of resources (ports, queues, ...) is different,
so macros have been added to take the device version
into account.

This commit also cleans up a few issues in the original
dlb2 source:
- eliminate duplicate constant definitions
- removed unused constant definitions

Is this an intended change? why change the driver's name.

Yes, This is an intentional change.  We will be using the same driver name

going forward, regardless of the hardware version.

quoted

Internally, we know which version of the hardware is present.

Since the driver name is still driver/event/dlb2. Keep it as same
prefix scheme with other drivers.

Thanks,
Tim

Would it be acceptable to rename drivers/event/dlb2 to drivers/event/dlb?
We may have additional dlb devices in the pipeline, such as v3, and we would

really like

quoted

to have them all use a common name.

Makes sense to change to drivers/event/dlb. I think, we can make to
dlb when you
add v3 support. Now there is no need.

Hi Jerin,

I spoke to the team, and we would like to get this change in now. It happens that we have
several applications that use the eventdev API rte_event_dev_get_dev_id(const char *name).
Having a single name simplifies these applications, and also prevents customers from having to
update application source code every time a new dlb device is released.

Now that we removed drivers/event/dlb, Please rename
drivers/event/dlb2 as drivers/event/dlb.
and change EVDEV_DLB_NAME_PMD as dlb_event and submit the new patch
patches for v2.5.

Thanks,
Tim
