Hi Ed,
As far as I can see "single function with multiple port" support was
already there but this commit is fixing queue index usage for it, if
correct can you please update commit log accordingly? (with fixes line
etc..)
This also helps the fix to be backported to LTS versions.
btw, how this feature was working until now, when queue ids "0 to
ark_api_num_queues_per_port()" used for each port?
Was it not tested at all, or is there something changed in FW causing
this issue, if so is there any FW version dependency to this change?

These each are a new eth_dev, so nothing wrong for each to allocate
device private data, but if the only difference in private data is
'ark->qbase', it is possible to use 'eth_dev->process_private' for it,
which is per eth_dev. It is up to you.
Btw, how there are handled in the secondary process? (previous patch)
Since this code just creates new eth_dev, shouldn't secondary process
needs some code to find and re-use them?

it looks like 'num_queues' only used locally and not needed to be part
of device data, unless there is some more usage planned for future.

Hi Ferruh,
We had looked at providing this patch as an LTS backport, but there are
some ties to FPGA firmware which complicate its application. As this is a
uncommon net/ark feature we support users on an as-needed basis.
Thanks.
Ed.

Got it, you don't want this fix to be backported, that is OK.
Still, it is a fix right, instead of a new support, if so can you please
reflect this in the commit log?
Also below comments seems ignored, can you please response them?
Specially I am curious about how come this failed now, was it a testing
gap in your end or a FW change caused it, and if it is a FW change this
may break previous FW support, right?

Hi Ed,
As far as I can see both primary and secondary process continues to run
after this point, and below there are a few places that updates
'eth_dev->data'.
'eth_dev->data' is shared between primary and secondaries, so each
secondary will be overwriting the shared data.
Better usage is shared data only updated by primary process and
secondary processes use available values.
But 'eth_dev' is process specific and all primary and shared processes
must set fields of this struct.
You may need to re-order calls in function to make secondary quit after
'eth_dev' fields updated and before 'eth_dev->data' updated, to make
sure secondaries don't update shared data.

Hi ferruh,
We have limited support for secondary processes. This patch simply avoids
corrupting the FPGA state if a secondary process attaches.
Improved support for secondary processes is on our list, but we need a
strong customer driver for this feature.
An update patch is following soon.
Thanks for the review.
Ed.

Hi Ed,
I see new version just updates commit log, mentioning this is minimal
secondary process support, but current implementation is wrong, it is
not about minimal support or full support.
Like just below secondary process, there is following code:
``dev->data->mac_addrs = rte_zmalloc()``
so you are allocating memory and set it to exact same pointer for
primary and each secondaries. This is probably leaking memory and
secondaries overwriting existing mac config by pointing it to new memory
location.
And there are more `dev->data->xxx` modifications in the function, which
is cause unexpected result.
As mentioned in the previous review, you need to find proper location to
return from function for secondary processes.
Please try to fix the implementation, instead of trying to push it with
known errors.

Support the creation of multiple ports from one ark device via
the use of ark pmd extension, though the assignment of queues
to port.
Add unique dev_private data for each port.

Can you please update patch title as fix commit, and add Fixes line?
It can be good to add information to commit log that backport is not
desired, for LTS maintainers see and prevent backporting by mistake.

Why is this printing directly to stderr? IMO this should be RTE_LOG(ERR,
...)
