patch 'net/bnxt: skip timed Tx pacing setup when unsupported' has been queued to stable release 25.11.3

[Kevin Traynor]

Hi,

FYI, your patch has been queued to stable release 25.11.3

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 08/01/26. 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/bfb87c79c44532fc8cc36c232522bb6c068b2f8b

Thanks.

Kevin

Subject: [PATCH] net/bnxt: skip timed Tx pacing setup when unsupported

[ upstream commit edff93f638540783af448de1d40a365b9aee52a6 ]

Driver attempts to configure the TTX pacing TQM rings regardless
of firmware capabilities. When the card does not support timed TX
pacing the device fails to initialize.

Skip the TTX_PACING_TQM_RING backing store type when
BNXT_FW_CAP_TIMED_TX_PACING is not set. The capability is defined
but not set until timed TX pacing support is enabled, so the ring
type is unconditionally skipped on unaffected cards.

Fixes: fe2f715ca580 ("net/bnxt: support backing store v2")
