Subject: [dpdk-stable] patch 'net/bnxt: refactor multi-queue Rx configuration' has been queued to stable release 19.11.9
Date: Mon, 17 May 2021 18:21:07 +0200
Message-ID: <20210517162125.3178901-3-christian.ehrhardt@canonical.com> (raw)
In-Reply-To: <20210517162125.3178901-1-christian.ehrhardt@canonical.com>

Hi,

FYI, your patch has been queued to stable release 19.11.9

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 05/19/21. 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/cpaelzer/dpdk-stable-queue

This queued commit can be viewed at:
https://github.com/cpaelzer/dpdk-stable-queue/commit/1a03f070178a1b75ea0724fc6613e8a7eec00ba0

Thanks.

Christian Ehrhardt <christian.ehrhardt@canonical.com>

Subject: [PATCH] net/bnxt: refactor multi-queue Rx configuration

[ upstream commit 21b1677d87a23a9695be0cbcbdf38607a2d58f84 ]

Eliminate separate codepath/handling for single queue
as the multiqueue code path takes care of it as well.
The only difference being the end_grp_id being 1
now instead of 0 for single queue, but that does not matter
for single queue and does not alter any functionality.

Fixes: 6133f207970c ("net/bnxt: add Rx queue create/destroy")
