[dpdk-dev] [PATCH] drivers/crypto/octeontx: enable unbinding for the OcteonTx crypto engines

[Thierry Herbelot <thierry.herbelot@6wind.com>]

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.
