Hi Ed,

Can you please add some context to commit log, what was the problem, what was
its impact, how this is fixed?

Queue index was incorrectly incremented with port, which
caused swizzling of packet placement among queues. This manifested
when the number of configured ports was >1 and < nb_queues.

What is "swizzling of packet placement"?


'qidx' is used to set 'phys_qid', if what the name suggest is correct it is used
to access the actual physical queues.

How this was working if you are calculating physical queue indexes wrong?
(Of-course except port 0)

Are you actually fixing the multiple port support?

I can see port number ">1", but is the 'nb_queues' limitation real?

If there are 2 queues per port, and you are configuring 3 ports will the
original calculation be correct?

Queue index was incorrectly incremented with port, which
caused incorrect queue packet placement. This manifested
when port number was != 0.

Hi Ed,

Please add version tag, v#, to the subject prefix, that makes easy to trace the
patches, like this is v3 of the patchset.

Also changing patch title as:
net/ark: fix queue packet replacement


Series applied to dpdk-next-net/master, thanks.
