patch 'net/bnxt: recheck FW readiness if in reset process' 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/03a539bf175280b8b9927846f6f0633ce3311cc2

Thanks.

Subject: [PATCH] net/bnxt: recheck FW readiness if in reset process
Cc: Xueming Li <xuemingl at nvidia.com>

[ upstream commit 5591bb92ced3a841398eec4444f593a22b1ca6ea ]

If Firmware is still in reset process and returns the error
HWRM_ERR_CODE_HOT_RESET_PROGRESS, retry VER_GET command.
We have to do it in bnxt_handle_if_change_status().

Fixes: 0b533591238f ("net/bnxt: inform firmware about IF state changes")
