# Users must change the PortalGroup section(s) to match the IP addresses

# domain, bus, device, and function. The format is dddd:bb:dd.f, which is
# the same format displayed by lspci or in /sys/bus/pci/devices. The second
# argument is a "name" for the device that can be anything. The name
# is referenced later in the Subsystem section.
#
# Alternatively, the user can specify ClaimAllDevices. All
# NVMe devices will be claimed and named Nvme0, Nvme1, etc.

# Users may change this section to create a different number or size of

# Users may not want to use offload even it is available.
# Users may use the whitelist to initialize specified devices, IDS
