Hi,

FYI, your patch has been queued to stable release 19.11.13

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 07/09/22. 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/cpaelzer/dpdk-stable-queue

Subject: [PATCH] net/vhost: fix TSO feature default disablement

[ upstream commit 6d7046215a3da334bac77d2b06e5ae1c208f3ca4 ]

By default, TSO feature should be disabled because it requires
application's support to be functional as mentioned in the
documentation.

However, if "tso" devarg was not specified, the feature did
not get disabled.

This patch fixes this issue, so that TSO is disabled, even if
"tso=0" is not passed as devarg.

Fixes: e289400669d5 ("net/vhost: support TSO disabling")
