64 +       Supported Platforms
65 +===================
66 +This driver provides networking support for Freescale LS2085A, LS2088A
67 +DPAA2 SoCs.
68 +
69 +
70 +Architecture Overview
71 +=====================
72 +The Ethernet Switch in the DPAA2 architecture consists of several hardware
73 +resources that provide the functionality. These are allocated and
74 +configured via the Management Complex (MC) portals. MC abstracts most of
75 +these resources as DPAA2 objects and exposes ABIs through which they can
76 +be configured and controlled.
77 +
78 +For a more detailed description of the DPAA2 architecture and its object
79 +abstractions see:
80 +       drivers/staging/fsl-mc/README.txt
81 +
82 +The Ethernet Switch is built on top of a Datapath Switch (DPSW) object.

106 +Driver uses the switch device driver model and exposes each switch port as
107 +a network interface, which can be included in a bridge. Traffic switched
108 +between ports is offloaded into the hardware. Exposed network interfaces
109 +are not used for I/O, they are used just for configuration. This
110 +limitation is going to be addressed in the future.
111 +
112 +The DPSW can have ports connected to DPNIs or to PHYs via DPMACs.

132 +
133 +Creating an Ethernet Switch
134 +===========================
135 +A device is created for the switch objects probed on the MC bus. Each DPSW
136 +has a number of properties which determine the configuration options and
137 +associated hardware resources.
138 +
139 +A DPSW object (and the other DPAA2 objects needed for a DPAA2 switch) can
140 +be added to a container on the MC bus in one of two ways: statically,
141 +through a Datapath Layout Binary file (DPL) that is parsed by MC at boot
142 +time; or created dynamically at runtime, via the DPAA2 objects APIs.
143 +
144 +Features
145 +========
146 +Driver configures DPSW to perform hardware switching offload of
147 +unicast/multicast/broadcast (VLAN tagged or untagged) traffic between its
148 +ports.
149 +
150 +It allows configuration of hardware learning, flooding, multicast groups,
151 +port VLAN configuration and STP state.
152 +
153 +Static entries can be added/removed from the FDB.
154 +
155 +Hardware statistics for each port are provided through ethtool -S option.
