[dpdk-stable] patch 'net/sfc/base: reject automatic filter creation by users' has been queued to stable release 19.11.3

[luca.boccassi at gmail.com]

Hi,

FYI, your patch has been queued to stable release 19.11.3

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 05/21/20. 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/sfc/base: reject automatic filter creation by users

[ upstream commit fbf423bbf2d298e4fc0e3f3a0d498ddb8bada94b ]

The automatic filter priority may only be used by filter implementation,
so reject the attempts to create such filters by client drivers.

Fixes: f9565517ff4f ("net/sfc/base: import filters support")
