This supports an Ethernet switching core from Vitesse / Microsemi /
Microchip (VSC9959) which is part of the Ocelot family (a brand name),
and whose code name is Felix. The switch can be (and is) integrated on
different SoCs as a PCIe endpoint device.

The functionality is provided by the core of the Ocelot switch driver
(drivers/net/ethernet/mscc). In this regard, the current driver is an
instance of Microsemi's Ocelot core driver, with a DSA front-end. It
inherits its name from VSC9959's code name, to distinguish itself from
the switchdev ocelot driver.

The patch adds the logic for probing a PCI device and defines the
register map for the VSC9959 switch core, since it has some differences
in register addresses and bitfield mappings compared to the other Ocelot
switches (VSC7511, VSC7512, VSC7513, VSC7514).

The Felix driver declares the register map as part of the "instance
table". Currently the VSC9959 inside NXP LS1028A is the only instance,
but presumably it can support other switches in the Ocelot family, when
used in DSA mode (Linux running on the external CPU, and not on the
embedded MIPS).

In a few cases, some h/w operations have to be done differently on
VSC9959 due to missing bitfields.  This is the case for the switch core
reset and init.  Because for this operation Ocelot uses some bits that
are not present on Felix, the latter has to use a register from the
global registers block (GCB) instead.

Although it is a PCI driver, it relies on DT bindings for compatibility
with DSA (CPU port link, PHY library). It does not have any custom
device tree bindings, since we would like to minimize its dependency on
device tree though.

While it is entirely possible that this tagger format is in fact more
generic than just these 2 switch families, I don't have that knowledge.
The Seville switch in NXP T1040 has a similar frame format, but there
are enough differences (e.g. DEST field starts at bit 57 instead of 56)
that calling this file tag_vitesse.c is a bit of a stretch at the
moment. The frame format has been listed in a comment so that people who
add support for further Vitesse switches can rework this tagger while
keeping compatibility with Felix.

The "ocelot" name was chosen instead of "felix" because even the Ocelot
switch can act as a DSA device when it is used in NPI mode, and the Felix
tagger format is almost identical. Currently it is only used for the
Felix switch embedded in the NXP LS1028A chip.

The ABI for this tagger should be considered "not stable" at the moment.
The DSA tag is always placed before the Ethernet header and therefore,
we are using the long prefix for RX tags to avoid putting the DSA master
port in promiscuous mode. Once there will be an API in DSA for drivers
to request DSA masters to be in promiscuous mode unconditionally, we
will switch to the "no prefix" extraction frame header, which will save
16 padding bytes for each RX frame.

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.
