If the DSA API is going to allow drivers to do things such as:
- phy_config in dsa_ops :: port_probe
- phy_startup in dsa_ops :: port_enable
then it would actually be good if the ->port_probe() method would
actually be called in all cases before the ->port_enable() is.
Currently this is true for user ports, but not true for the CPU port,
because the CPU port does not have a udevice registered for it (this is
all part of DSA's design). So the current issue is that after
phy_startup has finished for the CPU port, its phydev->speed is an
uninitialized value, because phy_config() was never called for the
priv->cpu_port_fixed_phy, and it is precisely phy_config() who copies
the speed into the phydev in the case of the fixed PHY driver.
So we need to simulate a probing event for the CPU port by manually
calling the driver's ->port_probe() method for the CPU port.

In the current DSA switch driver API, only the udevice of the switch
(belonging to UCLASS_DSA) is exposed, as well as an "int port" argument.
So drivers do not have access to the udevice of individual ports
(belonging to UCLASS_ETH), one of the reasons being that not all ports
have an associated UCLASS_ETH udevice.
However, all DSA ports have an OF node, and in some cases the driver
needs a handle to it, for all ports including the CPU port. Example: the
following Linux per-port device tree property:
managed = "in-band-status";
states whether a port should operate with clause 37 in-band autoneg
enabled or not.
This patch exposes a function which can be called by individual drivers
as needed.

strncpy() simply bails out when copying a source string whose size
exceeds the destination string size, potentially leaving the destination
string unterminated.
One possible way to address is to pass DSA_PORT_NAME_LENGTH - 1 and a
previously zero-initialized destination string, but this is more
difficult to maintain.
The chosen alternative is to use strlcpy(), which properly limits the
copy len in the (srclen >= size) case to "size - 1", and which is also
more efficient than the strncpy() byte-by-byte implementation by using
memcpy. The destination string returned by strlcpy() is always NULL

Linux uses the prefix "ethernet" whereas u-boot uses "eth". This is from

$ grep "ethernet[0-9].*=.*&" arch/**/*dts{,i}|wc -l

In u-boot device trees both prefixes are used. Until recently the only
user of the ethernet alias was the sandbox test device tree. This
changed with commit fc054d563b ("net: Introduce DSA class for Ethernet
switches"). There, the MAC addresses are inherited based on the devices
sequence IDs which is in turn given by the device tree.
Before there are more users in u-boot and both worlds will differ even
more, rename the alias prefix to "ethernet" to match the linux ones.
Also adapt the test cases and rename any old aliases in the u-boot

On systems that use CONFIG_OF_LIVE, the "ofnode" type is defined
as const struct device_node *np, while on the flat DT systems it
is defined as a long of_offset into gd->fdt_blob.
It is desirable that the fixed PHY driver uses the higher-level
ofnode abstraction instead of parsing gd->fdt_blob directly,
because that enables it to work on live OF systems.
The fixed PHY driver has used a nasty hack since its introduction in
commit db40c1aa1c ("drivers/net/phy: add fixed-phy /
fixed-link support"),
which is to pass the long gd->fdt_blob offset inside int phydev->addr
(a value that normally holds the MDIO bus address at which the PHY
responds). Even ignoring the fact that the types were already
mismatched leading to a potential truncation (flat OF offset was
supposed to be a long and not an int), we really cannot extend this
hack any longer, because there's no way an int will hold the other
representation of ofnode, the struct device_node *np.
So we unfortunately need to do the right thing, which is to use the
framework introduced by Grygorii Strashko in
commit eef0b8a930 ("net: phy: add ofnode node to struct phy_device").
This will populate phydev->node for the fixed PHY.
Note that phydev->node will not be valid in the probe function, since
that is called synchronously from phy_device_create and we really have
no way of passing the ofnode directly through the phy_device_create API.
So we do what other drivers do too: we move the OF parsing logic from
the .probe to the .config method of the PHY driver. The new function
will be called at phy_config() time.
I do believe I've converted all the possible call paths for creating
a PHY with PHY_FIXED_ID, so there is really no reason to maintain
compatibility with the old logic of retrieving a flat OF tree offset
from phydev->addr. We just pass 0 to phydev->addr now.

When trying to port our mpc8309-based board to DM_ETH, on top of
Heiko's patches, I found that nothing in mdio-uclass.c seems to
support the use of a fixed-link subnode of the ethernet DT node. That
is, the ethernet node looks like
enet0: ethernet@2000 {
device_type = "network";
compatible = "ucc_geth";
...
fixed-link {
reg = <0xffffffff>;
speed = <100>;
full-duplex;
};
but the current code expects there to be phy-handle property. Adding
that, i.e.
phy-handle = <&enet0phy>;
enet0phy: fixed-link {
just makes the code break a few lines later since a fixed-link node
doesn't have a reg property. Ignoring the dtc complaint and adding a
dummy reg property, we of course hit "can't find MDIO bus for node
ethernet@2000" since indeed, the parent node of the phy node does not
represent an MDIO bus. So that's obviously the wrong path.
Now, in linux, it seems that the fixed link case is treated specially;
in the of_phy_get_and_connect() which roughly corresponds to
dm_eth_connect_phy_handle() we have
if (of_phy_is_fixed_link(np)) {
ret = of_phy_register_fixed_link(np);
...
} else {
phy_np = of_parse_phandle(np, "phy-handle", 0);
...
}
phy = of_phy_connect(dev, phy_np, hndlr, 0, iface);
And U-Boot's phy_connect() does have support for fixed-link
subnodes. Calling phy_connect() directly with NULL bus and a dummy
address does seem to make the ethernet work.
