Subject: [dpdk-stable] patch 'net/ixgbe: fix vector Rx' has been queued to LTS release 18.11.11
Date: Wed, 18 Nov 2020 16:35:39 +0000	[thread overview]
Message-ID: <20201118163558.1101823-53-ktraynor@redhat.com> (raw)
In-Reply-To: <20201118163558.1101823-1-ktraynor@redhat.com>

Hi,

FYI, your patch has been queued to LTS release 18.11.11

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 11/24/20. 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-queue

This queued commit can be viewed at:
https://github.com/kevintraynor/dpdk-stable-queue/commit/b7a03919c8e63b053c7453888e6a4fc325bf2221

Thanks.

Kevin.

Subject: [PATCH] net/ixgbe: fix vector Rx
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

[ upstream commit 5a3cca342417f7d4be4ac4b6225ca509617777c4 ]

The limitation of burst size in vector rx was removed, since it should
retrieve as much received packets as possible. And also the scattered
receive path should use a wrapper function to achieve the goal of
burst maximizing.

Bugzilla ID: 516
Fixes: b20971b6cca0 ("net/ixgbe: implement vector driver for ARM")
Fixes: 0e51f9dc4860 ("net/ixgbe: rename x86 vector driver file")
