Marvell Octeon NIC Accelerator Support

--------------------------------
Dell Open RAN Accelerator (DORA)
--------------------------------
The Dell Open RAN Accelerator (DORA) utilizes the OCTEON Fusion CNF95xx chipset
from Marvell and its design deviates from that of a standard network interface
card (NIC), which requires specialized configuration. Unlike conventional NICs,
the |DORA| requires the deployment of dedicated application software prior to
its operational functionality. This application software assumes responsibility
for:
- loading the octeon kernel module
- bringing up the |DORA| card on every boot
- making the VFs available as resources to Kubernetes
- bringing the |DORA| card down
- back up if a driver upgrade is desired
Any attempt to use the 'system' CLI to add ``pci-sriov`` VF interfaces will not
succeed as drivers are not being loaded by default at boot time, although it is
possible to configure it as a PCI passthrough PF interface.
