Hi,
FYI, your patch has been queued to stable release 20.11.1
Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 02/07/21. 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/cee5f387737a1208eed369f423d96320a970f21f
Thanks.
Luca Boccassi

Subject: [PATCH] net/bnxt: make offload flags mapping per-ring
[ upstream commit d5bbd722469b61c0bc8bc95c51c46b80de045149 ]
Refactor offload flags mapping table to be dynamic and
per-ring instead of static and global.
