[dpdk-stable] patch 'net/vhost: restore pseudo TSO support' has been queued to stable release 20.11.2

[Xueming Li]

Hi,

FYI, your patch has been queued to stable release 20.11.2

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 06/14/21. 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/steevenlee/dpdk

This queued commit can be viewed at:
https://github.com/steevenlee/dpdk/commit/4079bce204905af72483e818ef2d01138d2cfe3b

Thanks.

Subject: [PATCH] net/vhost: restore pseudo TSO support
Cc: Luca Boccassi <bluca at debian.org>

[ upstream commit 1583ad5b5e3e75285c566b943eda7d7cbb4d2825 ]

The net/vhost PMD does not comply with the ethdev offload API as it does
not report Rx/Tx offload capabilities wrt TSO and checksum offloading.
On the other hand, the net/vhost PMD lets guest negotiates TSO and
checksum offloading.

Changing the behavior for Rx/Tx offload flags handling won't
improve/fix this situation and will break applications that might have
been relying on implicit support of TSO in this driver.

Revert this behavior change until we have a complete fix.

Fixes: ca7036b4af3a ("vhost: fix offload flags in Rx path")
