Subject: [dpdk-stable] [PATCH] drivers/crypto/octeontx: enable unbinding for the OcteonTx crypto engines
Date: Wed, 11 Sep 2019 18:07:29 +0200
Message-ID: <> (raw)

Like for Ethernet ports, the OcteonTx crypto engines must first be unbound
from their kernel module, then rebound to vfio-pci, before being usable
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: bfe2ae495ee268 ('crypto/octeontx: add PMD skeleton')
