[f-nsp] ICX6650 / ICX7750 queue mapping

[Robert Wiebusch]

Here are the FastIron/ICX control protocols and the queues they are mapped to.  These are not configurable.  Only the ICX 6430 has 4 hardware queues, all other ICX have 8 priority queues per port.

Subject: [f-nsp] ICX6650 / ICX7750 queue mapping

Curious if anyone has a doc that shows default queue mappings on ICX platforms. 6650 appears to have 8 queues per interface.

With default config, most traffic is 0 (so I presume that's BE), but I see traffic in 6 and 7 as well. I would guess that it's mapping 6/7 to network control depending on what type of packet, but it would be nice to know for sure. Some docs say 7 is used for stacking depending on platform, but although we're not stacking we see lots of packets in that queue.

Ideally I'm looking for the ICX equivalent docs:

.. which show default queue types per platform + which type of packets generated from the device are in which queue.

I've configured some queue mappings to map pretty much everything AWAY from queue 7, yet it still gets hits, so who knows. This particular config is on a 6650 running 8.0.10m.
