+
+	Supported Platforms
+===================
+This driver provides networking support for Freescale LS2085A, LS2088A
+DPAA2 SoCs.
+
+
+Architecture Overview
+=====================
+The Ethernet Switch in the DPAA2 architecture consists of several hardware
+resources that provide the functionality. These are allocated and
+configured via the Management Complex (MC) portals. MC abstracts most of
+these resources as DPAA2 objects and exposes ABIs through which they can
+be configured and controlled.
+
+For a more detailed description of the DPAA2 architecture and its object
+abstractions see:
+	drivers/staging/fsl-mc/README.txt
+
+The Ethernet Switch is built on top of a Datapath Switch (DPSW) object.
+

+
+Driver uses the switch device driver model and exposes each switch port as
+a network interface, which can be included in a bridge. Traffic switched
+between ports is offloaded into the hardware. Exposed network interfaces
+are not used for I/O, they are used just for configuration. This
+limitation is going to be addressed in the future.
+
+The DPSW can have ports connected to DPNIs or to PHYs via DPMACs.

+
+Creating an Ethernet Switch
+===========================
+A device is created for the switch objects probed on the MC bus. Each DPSW
+has a number of properties which determine the configuration options and
+associated hardware resources.
+
+A DPSW object (and the other DPAA2 objects needed for a DPAA2 switch) can
+be added to a container on the MC bus in one of two ways: statically,
+through a Datapath Layout Binary file (DPL) that is parsed by MC at boot
+time; or created dynamically at runtime, via the DPAA2 objects APIs.
+
+Features
+========
+Driver configures DPSW to perform hardware switching offload of
+unicast/multicast/broadcast (VLAN tagged or untagged) traffic between its
+ports.
+
+It allows configuration of hardware learning, flooding, multicast groups,
+port VLAN configuration and STP state.
+
+Static entries can be added/removed from the FDB.
+
+Hardware statistics for each port are provided through ethtool -S option.

+* Add I/O capabilities on switch port netdevices. This will allow control
+traffic to reach the CPU.
+* Add ACL to redirect control traffic to CPU.
+* Add support for displaying learned FDB entries
+* MC firmware uprev; the DPAA2 objects used by the Ethernet Switch driver
