Marvell Prestera 98DX326x integrates up to 24 ports of 1GbE with 8
ports of 10GbE uplinks or 2 ports of 40Gbps stacking for a largely
wireless SMB deployment.

Prestera Switchdev is a firmware based driver which operates via PCI
bus. The driver is split into 2 modules:

    - prestera_sw.ko - main generic Switchdev Prestera ASIC related logic.

    - prestera_pci.ko - bus specific code which also implements firmware
                        loading and low-level messaging protocol between
                        firmware and the switchdev driver.

This driver implementation includes only L1 & basic L2 support.

The core Prestera switching logic is implemented in prestera.c, there is
an intermediate hw layer between core logic and firmware. It is
implemented in prestera_hw.c, the purpose of it is to encapsulate hw
related logic, in future there is a plan to support more devices with
different HW related configurations.

The firmware has to be loaded each time device is reset. The driver is
loading it from:

    /lib/firmware/marvell/prestera_fw_img.bin

The firmware image version is located within internal header and consists
of 3 numbers - MAJOR.MINOR.PATCH. Additionally, driver has hard-coded
minimum supported firmware version which it can work with:

    MAJOR - reflects the support on ABI level between driver and loaded
            firmware, this number should be the same for driver and
            loaded firmware.

    MINOR - this is the minimal supported version between driver and the
            firmware.

    PATCH - indicates only fixes, firmware ABI is not changed.

The firmware image will be submitted to the linux-firmware after the
driver is accepted.

The following Switchdev features are supported:

    - VLAN-aware bridge offloading
    - VLAN-unaware bridge offloading
    - FDB offloading (learning, ageing)
    - Switchport configuration

CPU RX/TX support will be provided in the next contribution.
