Hi,

FYI, your patch has been queued to stable release 20.11.3

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 07/28/21. 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/3e6a9fa0e2a5398cf0bf2e5372091b28b7b1d00e

Thanks.

Luca Boccassi

Subject: [PATCH] net/hinic/base: fix LRO

[ upstream commit 68fa836d0ff83229e1404f1274c90e1bff2475c8 ]

The Rx queue must config as ceq disables, and must set MSI-X
state disabled. Otherwise when LRO is enables, there will be
problems with packet aggregation because of firmware.

Fixes: 9d02f40d6503 ("net/hinic: fix LRO")
