[dpdk-stable] patch 'net/ena: fix passing RSS hash to mbuf' has been queued to LTS release 16.11.9

[Luca Boccassi]

Hi,

FYI, your patch has been queued to LTS release 16.11.9

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 10/31/18. 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. If the code is different (ie: not only metadata diffs), due for example to
a change in context or macro names, please double check it.

Thanks.

Luca Boccassi

Subject: [PATCH] net/ena: fix passing RSS hash to mbuf

[ upstream commit e5df9f33db00eb9d322abaefff30da74fd0e625d ]

The driver was passing to the mbuf Rx queue ID instead of hash received
from the device. Now, the RSS hash from the Rx descriptor is being set.

Fixes: 1173fca25af9 ("ena: add polling-mode driver")
