-+DPAA2 Ethernet Switch driver
-+============================
-+
-+This file provides documentation for the DPAA2 Ethernet Switch driver
-+
-+
-+Contents

-+ Architecture Overview
-+ Creating an Ethernet Switch
-+ Features
-+
-+
-+ 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.
-+
-+Configuration interface:

-+ ------
-+
-+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
-+need to be kept in sync with binary interface changes in MC
-+* refine README file
-+* cleanup
-+
-+NOTE: At least first three of the above are required before getting the
-+DPAA2 Ethernet Switch driver out of staging. Another requirement is that
-+the fsl-mc bus driver is moved to drivers/bus and dpio driver is moved to
-+drivers/soc (this is required for I/O).
