- 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.
+++ /dev/null
-* 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 multiple FDBs and switch port partitioning
-* 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
-dpio driver is moved to drivers/soc (this is required for I/O).
