[dpdk-stable] patch 'net/netvsc: fix RSS offload flag' has been queued to stable release 19.11.1

[luca.boccassi at gmail.com]

Hi,

FYI, your patch has been queued to stable release 19.11.1

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 02/13/20. 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/netvsc: fix RSS offload flag

[ upstream commit b1cf08ae095026ec9befe2aeddf4ecd1785a37a6 ]

The change to add OFFLOAD_RSS_HASH broke use of netvsc PMD
with testpmd. The netvsc driver fails during configure step:

	Configuring Port 1 (socket 0)
	hn_dev_configure(): unsupported RX offload: 0x80000

Fixes: 5d308972954c ("ethdev: add mbuf RSS update as an offload")
