[dpdk-stable] patch 'net/virtio: remove remaining simple Tx related stuff' has been queued to LTS release 18.11.6

[Kevin Traynor]

Hi,

FYI, your patch has been queued to LTS release 18.11.6

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 11/29/19. 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/038f992817028b24cbfd3e676ec6d3d61b779d72

Thanks.

Kevin.

Subject: [PATCH] net/virtio: remove remaining simple Tx related stuff

[ upstream commit 1d2aa48b876148715680c9a1d69c195a929bad14 ]

The simple Tx path in virtio has been removed in below commit.
This patch removes an undefined function declaration of simple
Tx and all related descriptions in the doc.

Fixes: 57f818963d80 ("net/virtio: remove simple Tx path")
