Hi,

FYI, your patch has been queued to stable release 22.11.11

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 11/22/25. 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/bluca/dpdk-stable

This queued commit can be viewed at:
https://github.com/bluca/dpdk-stable/commit/55eaf1cf8f35eb42e14c7bd985ea257993f2bab0

Thanks.

Subject: [PATCH] common/cnxk: fix max number of SQB buffers in clean up

[ upstream commit f3c15bb6062475a62451c62ca2c5c9a5e12706c8 ]

By default, SQB pool is created with max (512 buffers) +
extra threshold buffers and aura limit is set to 512 + thr.

But while clean up, aura limit is reset to MAX (512 buffers)
only before destroying the pool.

Hence while destroying the pool, only 512 buffers are cleaned
from aura and extra threshold buffers are left as it is.

At later stage if same SQB pool is created then H/W
throws error for extra threshold buffers that it is already
in pool.

Fixes: 780f90e951a5 ("common/cnxk: restore NIX SQB pool limit before destroy")
