[Kevin Traynor]

Hi,

FYI, your patch has been queued to stable release 21.11.1

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 02/26/22. 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/kevintraynor/dpdk-stable

This queued commit can be viewed at:
https://github.com/kevintraynor/dpdk-stable/commit/393d0580db79f9f210b5ed751982f476a9e9f066

Thanks.

Subject: [PATCH] doc: fix dlb2 guide

[ upstream commit 7fe2d346af2f3cae0e94347861cdfa412af39fc2 ]

Number of direct credits, atomic inflight and history list are
updated to DLB2.0 supported sizes. As DLB2.0 does not provide
dev arg to override the default per-queue atomic inflight
allocation, it is removed from the documentation.

Fixes: f3cad285bb88 ("event/dlb2: add infos get and configure")
