[dpdk-stable] patch 'net/sfc: allow to query RSS key and HF in isolated mode' has been queued to stable release 18.08.1

[Kevin Traynor]

Hi,

FYI, your patch has been queued to stable release 18.08.1

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 11/27/18. 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.

Kevin Traynor

Subject: [PATCH] net/sfc: allow to query RSS key and HF in isolated mode

[ upstream commit 453e1d4baad9262391eaef15812ade9af1f15a3f ]

Isolated mode prevents global RSS from being enabled and configured.
However, an application may need to query default RSS key and hash
functions when a flow rule with RSS action is added which does not
contain custom RSS key or hash function choice. In this case
global RSS key and hash functions will be used to handle the rule,
and there should be some way for the application to query these
global default settings to clarify expectations on the traffic
distribution.

Fixes: 84a9b48128c1 ("net/sfc: support flow API isolated mode")
