This commit adds more clarity to handling of TC_CLSMATCHALL_REPLACE and
TC_CLSMATCHALL_DESTROY events by calling newly added *_mall_*() handlers
instead of directly calling SPAN API.
This also extracts matchall rules management out of SPAN API since SPAN
is a hardware module which is used to implement 'matchall egress mirred'
action only.

Add prestera_router_hw.c. This file contains functions, which track HW
objects relations and links. This include implicity creation of objects,
that needed by requested one and implicity removing of objects, which
reference counter is became zero.
We need this layer, because kernel callbacks not always mapped to
creation of single HW object. So let it be two different layers - one
for subscribing and parsing kernel structures, and another
(prestera_router_hw.c) for HW objects relations tracking.
There is two types of objects on router_hw layer:
- Explicit objects (rif_entry) : created by higher layer.
- Implicit objects (vr) : created on demand by explicit objects.

Add prestera_router.c, which contains code to subscribe/unsubscribe on
kernel notifiers for router. This handle kernel notifications,
parse structures to make key to manipulate prestera_router_hw's objects.
Also prestera_router is container for router's objects database.

- Introduce matchall filter support
- Add SPAN API to configure port mirroring.
- Add tc mirror action.
At this moment, only mirror (egress) action is supported.
Example:
tc filter ... action mirred egress mirror dev DEV

Add ACL infrastructure for Prestera Switch ASICs family devices to
offload cls_flower rules to be processed in the HW.
ACL implementation is based on tc filter api. The flower classifier
is supported to configure ACL rules/matches/action.
Supported actions:
- drop
- trap
- pass
Supported dissector keys:
- indev
- src_mac
- dst_mac
- src_ip
- dst_ip
- ip_proto
- src_port
- dst_port
- vlan_id
- vlan_ethtype
- icmp type/code

The following features are supported:
- VLAN-aware bridge offloading
- VLAN-unaware bridge offloading
- FDB offloading (learning, ageing)
- Switchport configuration
Currently there are some limitations like:
- Only 1 VLAN-aware bridge instance supported
- FDB ageing timeout parameter is set globally per device

The ethtool API provides support for the configuration of the following
features: speed and duplex, auto-negotiation, MDI-x, forward error
correction, port media type. The API also provides information about the
port status, hardware and software statistic. The following limitation
exists:
- port media type should be configured before speed setting
- ethtool -m option is not supported
- ethtool -p option is not supported
- ethtool -r option is supported for RJ45 port only
- the following combination of parameters is not supported:
ethtool -s sw1pX port XX autoneg on
- forward error correction feature is supported only on SFP ports, 10G
speed
- auto-negotiation and MDI-x features are not supported on
Copper-to-Fiber SFP module

Add PCI interface driver for Prestera Switch ASICs family devices, which
provides:
- Firmware loading mechanism
- Requests & events handling to/from the firmware
- Access to the firmware on the bus level
The firmware has to be loaded each time the device is reset. The driver
is loading it from:
/lib/firmware/mrvl/prestera/mvsw_prestera_fw-v{MAJOR}.{MINOR}.img
The full firmware image version is located within the 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 minimum supported version between driver and the
firmware.
PATCH - indicates only fixes, firmware ABI is not changed.
Firmware image file name contains only MAJOR and MINOR numbers to make
driver be compatible with any PATCH version.

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.
The current implementation supports only boards designed for the Marvell
Switchdev solution and requires special firmware.
The core Prestera switching logic is implemented in prestera_main.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.
This patch contains only basic switch initialization and RX/TX support
over SDMA mechanism.
Currently supported devices have DMA access range <= 32bit and require
ZONE_DMA to be enabled, for such cases SDMA driver checks if the skb
allocated in proper range supported by the Prestera device.
Also meanwhile there is no TX interrupt support in current firmware
version so recycling work is scheduled on each xmit.
Port's mac address is generated from the switch base mac which may be
provided via device-tree (static one or as nvme cell), or randomly
generated. This is required by the firmware.
