> +CNXK product families can have a use case to allow PF and VF
PF and VF -> RVU PF and RVU VF
> +applications to communicate using mailboxes and also get notified of
Applications-> driver
> +any interrupt that may occur on the device.
> +Hence, a new raw device driver is added for such RVU LF devices.

> +Features
> +--------
> +
> +The RVU LF device implements following features in the rawdev API:
> +
> +- Register mailbox callbacks for the other side to process mailboxes.
> +- Register interrupt handler callbacks.
> +- Process mailbox.
> +- Set range of message IDs allowed for communication.
Please update each lines in the respective patch.
Also, please wire this file to doc/guides/platform/cnxk.rst like other cnxk drivers

> +The RVU LF devices will need to be bound to a user-space IO driver for use.
> +The script ``dpdk-devbind.py`` included with DPDK can be used to view
> +the state of the devices and to bind them to a suitable DPDK-supported
> +kernel driver. When querying the status of the devices, they will
