patch 'net/bnxt: fix compatibility with some old firmwares' 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/ff874e673ad8161edf3c3eedc6a7c61a86f05076

Thanks.

Subject: [PATCH] net/bnxt: fix compatibility with some old firmwares
Cc: Xueming Li <xuemingl at nvidia.com>

[ upstream commit a43d0129579034af06314b6603d92a866d809eeb ]

This reverts commit 3972281f47b2cc0cf844698885f0e6b4228c0975.

Reported by Red Hat QE: with older firmware versions (at least versions
20.6.112.0 and 20.6.143.0), initialisation never succeeds following this
change.
Revert it for now, waiting for a more complete fix.

Fixes: 3972281f47b2 ("net/bnxt: fix device readiness check")
