[dpdk-stable] patch 'crypto/octeontx2: add kmod dependency info' 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 02/19/20. 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] crypto/octeontx2: add kmod dependency info

[ upstream commit 02ba37237612f6d9a30b48e232b3dcd2cafe4e60 ]

Like for OCTEON TX, the OCTEON TX2 crypto engines must
first be unbound from their kernel module, then rebound to
vfio-pci, before being used in DPDK.

As this capability is detected at runtime by dpdk-pmdinfo,
add the info in the PMD registering directives.

Then an external script can be used for bind and unbind.

Fixes: 2f8a1b963eb77 ("crypto/octeontx2: add PMD skeleton")
