Hi,

FYI, your patch has been queued to stable release 19.11.6

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

This queued commit can be viewed at:
https://github.com/bluca/dpdk-stable/commit/d9d122771dd5f78c3be9c955a0ff53332729bbe9

Thanks.

Luca Boccassi

Subject: [PATCH] net/bnxt: fix resetting mbuf data offset

[ upstream commit 3cefa72935fde04824fdfbee9c435c08278ab3c2 ]

Reset mbuf->data_off before handing the Rx packet to the application.
We were not doing this in the TPA path. It can cause applications
using this field for post processing to work incorrectly.

Fixes: 0958d8b6435d ("net/bnxt: support LRO")
