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

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.
