[dpdk-stable] patch 'kni: abort when IOVA is not PA' has been queued to LTS release 18.11.3

[Kevin Traynor <ktraynor@redhat.com>]

Hi,

FYI, your patch has been queued to LTS release 18.11.3

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 09/03/19. 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.

Queued patches are on a temporary branch at:
https://github.com/kevintraynor/dpdk-stable-queue

This queued commit can be viewed at:
https://github.com/kevintraynor/dpdk-stable-queue/commit/5c94659a276a981fdb820bf15bb00860c8eed7a1

Thanks.

Kevin Traynor

Subject: [PATCH] kni: abort when IOVA is not PA

[ upstream commit fe8fc6b0b7eaf9078d804d57221000a494753997 ]

If a forced iova-mode has been passed at init, kni is not supposed to
work.

Fixes: 075b182b54ce ("eal: force IOVA to a particular mode")
