[dpdk-stable] patch 'net/hns3: add RSS hash offload to Rx configuration' has been queued to stable release 19.11.4

[luca.boccassi at gmail.com]

Hi,

FYI, your patch has been queued to stable release 19.11.4

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 07/26/20. 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.

Thanks.

Luca Boccassi

Subject: [PATCH] net/hns3: add RSS hash offload to Rx configuration

[ upstream commit fdae939696a09b4010df004be06c491d9294e319 ]

Rx offload flag `DEV_RX_OFFLOAD_RSS_HASH` which can be used to
enable/disable PMDs write to `rte_mbuf::hash::rss`. The hns3 PMD driver
already can notify the validity of `rte_mbuf::hash:rss` to the
application by enabling `PKT_RX_RSS_HASH` flag in `rte_mbuf::ol_flags`.

Fixes: 19a3ca4c99cf ("net/hns3: add start/stop and configure operations")
Fixes: c37ca66f2b27 ("net/hns3: support RSS")
