patch 'net/bnxt: fix switch domain allocation' has been queued to stable release 21.11.2

[Kevin Traynor]

Hi,

FYI, your patch has been queued to stable release 21.11.2

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 06/30/22. 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/kevintraynor/dpdk-stable

This queued commit can be viewed at:
https://github.com/kevintraynor/dpdk-stable/commit/7991efd0ba3f4dd49e1c501b323215e5b1c65e58

Thanks.

Kevin

Subject: [PATCH] net/bnxt: fix switch domain allocation

[ upstream commit aef3baca157d8202c26c5e034a9ab920da60d414 ]

Allocate switch domain after the trusted VF capability is queried
from the FW. Currently we are calling the function earlier.
Since the switch domain is allocated only for PFs or trusted VF,
the current location of code fails to allocate the domain during init.
But during cleanup we try to free the domain incorrectly.
Fix the behavior by changing the sequence of function calls.

Fixes: 3127f99274b67 ("net/bnxt: refactor init/uninit")
