> Like for Ethernet ports, the OCTEON TX 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.
