patch 'net/sfc: export pick transfer proxy callback to representors' has been queued to stable release 22.11.2

[Xueming Li]

Hi,

FYI, your patch has been queued to stable release 22.11.2

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 03/01/23. 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://git.dpdk.org/dpdk-stable/log/?h=22.11-staging

This queued commit can be viewed at:
https://git.dpdk.org/dpdk-stable/commit/?h=22.11-staging&id=e4f7453ec1c7efacf4ae92fdae243ed9a3410840

Thanks.

Subject: [PATCH] net/sfc: export pick transfer proxy callback to representors
Cc: Xueming Li <xuemingl at nvidia.com>

[ upstream commit d5a478f3b2ba3b2e6efebf36219eaff79b52bad1 ]

Currently, the "pick transfer proxy ethdev" callback is only
advertised for non-representor (in example, main PF) ethdevs.
That does not sit well with the original idea of this method,
which is to let applications discover the privileged port to
use for transfer flow management instead of any given ethdev.
Applications trying to leverage this API on sfc representors
receive an error and cannot configure transfer flow offloads.

Fix the problem by exporting the method to representor ports.

Fixes: 26706314d418 ("net/sfc: implement transfer proxy port callback")
