Hi,

FYI, your patch has been queued to stable release 20.11.1

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 02/07/21. 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/bluca/dpdk-stable

This queued commit can be viewed at:
https://github.com/bluca/dpdk-stable/commit/61593e139ef88379decb94fb18a9fd4c4ebaae0a

Thanks.

Subject: [PATCH] app/testpmd: fix queue reconfig request on Rx split update

[ upstream commit 293ca0aaafaaed4b0ff96f5fec30fbd54f8e9cb3 ]

There is the "set rxpkts" command in the testpmd interactive mode,
it configures the segment sizes to split the packet on receiving.
The mentioned segment sizes are provided on the Rx queue setup
as part of queue configuration. Hence, to take the rxpkts command
into effect the Rx queues must be explicitly reconfigured.

The explained above is related to the "set rxoffs" as well.

The patch sets the queue reconfiguration request flag for
all devices once Rx split settings are updated, to take
the changes into effect the port(s) should be restarted.

Fixes: 0f2096d7ab36 ("app/testpmd: add rxpkts commands and parameters")
Fixes: 91c78e090eed ("app/testpmd: add rxoffs commands and parameters")
