++DPAA2 Ethernet Switch driver

++ 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.
++

++ ------
++
++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).
