Hi Shepard, Ed,
The patchset looks good, I can squash them into single patch while merging.
I don't know how major this new device is, if it is an important one you
may want to introduce it in the release notes too, what do think?
And if you will send a new version, can you please put previous doc
patch [1] and this to the same patchset since this one depends previous
doc patch to apply cleanly.
Thanks.

Thank you Ferruh,
We have rolled all changes, including your suggestion on the Release Note,
into the four distinct patches in this patchset which collectively brings
the
ark PMD up to date for this new capability.

It is possible to squash 2/4, 3/4 & 4/4 into single patch, I can do it
while merging.
In the patch title it mentions 'PCIe allowlist', this is not a kind of
allow list, this is list of PCI ids supported by driver, so I can update
patch title as following while merging if there won't be a new version:
"net/ark: support Arkville FX2 device"

Hi Ferruh,
Yes, there will probably be next versions in the future. If you don't mind
making the marker length adjustment, that would be great.
Regarding MBUF (re)sizing - Arkville supports the ability to configure or
reconfigure the MBUF size used on a per-queue basis. This feature is useful
when the are conflicting motivations for using smaller/larger MBUF sizes.
For example, user can switch a queue to use a size best for that
queue's application workload.

Hi Ferruh,
If you dont mind squashing 2/4 3/4 4/4 together, that would be great.
Thank you for correcting on the allowlist, s..b "supported PCIe ids list"
instead.
best, Shep

Application can allocate multiple mempool with different sizes and set
these to specific queues, this is same for all PMDs, is ark PMD doing
something specific here? Or are you referring to something else?
And what does 'dynamic' emphasis means here?

Yes, what is different here is that the MBUF size is communicated from the
PMD to the hardware which *changes its behavior* of data motion to
optimize throughput and latency as a function of that setting. And it does
that per-queue. And can be done at runtime (that's the dynamic part). ...
To the best our knowledge, other PMDs use this as a host-software setting
only - and their DPDK naive DMA engines just use the same fixed settings
(respecting PCIe, of course).
Hope that helps. If it is contentious in any way, we are fine with
removing that line. We added it as users have remarked it is a unique
capability they think we should point out.

Just trying to clarify the feature you are referring, this helps to your
users too.
I was thinking this feature is already granted and if there is more
details in the documented feature, but it is not granted and OK to keep
as it is.
