The dpaa2-eth driver now has support for connecting to its associated
PHY device found through standard OF bindings.
This happens when the DPNI object (that the driver probes on) gets
connected to a DPMAC. When that happens, the device tree is looked up by
the DPMAC ID, and the associated PHY bindings are found.
The old logic of handling the net device's link state by hand still
needs to be kept, as the DPNI can be connected to other devices on the
bus than a DPMAC: other DPNI, DPSW ports, etc. This logic is only
engaged when there is no DPMAC (and therefore no phylink instance)
attached.
The MC firmware support multiple type of DPMAC links: TYPE_FIXED,
TYPE_PHY. The TYPE_FIXED mode does not require any DPMAC management from
Linux side, and as such, the driver will not handle such a DPMAC.
Although PHYLINK typically handles SFP cages and in-band AN modes, for
the moment the driver only supports the RGMII interfaces found on the
LX2160A. Support for other modes will come later.

Export detailed driver counters through debugfs.
Statistics already available in ethtool are presented in a
structured manner. Includes per-core, per-FQ and per-channel statistics.
Also transition from module_fsl_mc_driver to explicit module_init/exit
in order to create the debugfs directory besides registering the driver.

The DPAA2 Ethernet driver supports Freescale/NXP SoCs with DPAA2
(DataPath Acceleration Architecture v2). The driver manages
network objects discovered on the fsl-mc bus.
