patch 'net/iavf: fix HW ring scan method selection' has been queued to stable release 20.11.6

[Xueming Li]

Hi,

FYI, your patch has been queued to stable release 20.11.6

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 06/23/22. So please
shout if anyone has objections.

Also note that after the patch there's a diff of the upstream commit vs the
patch applied to the branch. This will indicate if there was any rebasing
needed to apply to the stable branch. If there were code changes for rebasing
(ie: not only metadata diffs), please double check that the rebase was
correctly done.

Queued patches are on a temporary branch at:
https://github.com/steevenlee/dpdk

This queued commit can be viewed at:
https://github.com/steevenlee/dpdk/commit/236835c94ff7bf830e2f75c8c8f00ab0a0779c35

Thanks.

Subject: [PATCH] net/iavf: fix HW ring scan method selection
Cc: Xueming Li <xuemingl at nvidia.com>

[ upstream commit 070ef4e6c815bf7f4647070acf1ed4025e0512e9 ]

When setup Rx queue, the rxdid would be changed if it's
"IAVF_RXDID_LEGACY_0/1", that caused the scan HW ring used the wrong
function 'iavf_rx_scan_hw_ring_flex_rxd()'.

Ignore the rxdid changed when equals "IAVF_RXDID_LEGACY_0/1".

Fixes: 0ed16e01313e ("net/iavf: fix function pointer in multi-process")
