There are 2 issues with the blamed commit.
1. When the phy is initialized, it would enable the disabled of UDPv4
checksums. The UDPv6 checksum is already enabled by default. So when
1-step is configured then it would clear these flags.
2. After the 1-step is configured, then if 2-step is configured then the
1-step would be still configured because it is not clearing the flag.
So the sync frames will still have origin timestamps set.
Fix this by reading first the value of the register and then
just change bit 12 as this one determines if the timestamp needs to
be inserted in the frame, without changing any other bits.

On reworking and splitting the at803x driver, in splitting function of
at803x PHYs it was added a NULL dereference bug where priv is referenced
before it's actually allocated and then is tried to write to for the
is_1000basex and is_fiber variables in the case of at8031, writing on
the wrong address.
Fix this by correctly setting priv local variable only after
at803x_probe is called and actually allocates priv in the phydev struct.

read_poll_timeout inside phy_read_poll_timeout can set val negative

Supposedly, commit 4ec732951702 ("net: phylib: fix phy_read*_poll_timeout()")
should fix problems with wrong-signed vals, but I do not see how
as val is sent to phy_read as is and __val = phy_read (not val)
is checked for sign.
Change val type for signed to allow better error handling as done in other
phy_read_poll_timeout callers. This will not fix any error handling
by itself, but allows, for example, to modify cond with appropriate

In order for EEE to operate, both the MAC and the PHY need to support
it, similar to how pause works. With some exception - a number of PHYs
have SmartEEE or AutoGrEEEn support in order to provide some EEE-like
power savings with non-EEE capable MACs.
Copy the pause concept and add the call phy_support_eee() which the MAC
makes after connecting the PHY to indicate it supports EEE. phylib will
then advertise EEE when auto-neg is performed.

The MAC driver changes its EEE hardware configuration in its
adjust_link callback. This is called when auto-neg
completes. Disabling EEE via eee_enabled false will trigger an
autoneg, and as a result the adjust_link callback will be called with
phydev->enable_tx_lpi set to false. Similarly, eee_enabled set to true
and with a change of advertised link modes will result in a new
autoneg, and a call the adjust_link call.
If set_eee is called with only a change to tx_lpi_enabled which does
not trigger an auto-neg, it is necessary to call the adjust_link
callback so that the MAC is reconfigured to take this change into
account.
When setting phydev->enable_tx_lpi, take both eee_enabled and
tx_lpi_enabled into account, so the MAC drivers just needs to act on
phydev->enable_tx_lpi and not the whole EEE configuration.
The same check should be done for tx_lpi_timer too.

MAC drivers which support EEE need to know the results of the EEE
auto-neg in order to program the hardware to perform EEE or not. The
oddly named phy_init_eee() can be used to determine this, it returns 0
if EEE should be used, or a negative error code,
e.g. -EOPPROTONOTSUPPORT if the PHY does not support EEE or negotiate
resulted in it not being used.
However, many MAC drivers get this wrong. Add phydev->enable_tx_lpi
which indicates the result of the autoneg for EEE, including if EEE is
administratively disabled with ethtool. The MAC driver can then access
this in the same way as link speed and duplex in the adjust link
callback. If enable_tx_lpi is true, the MAC should send low power
indications and does not need to consider anything else with respect
to EEE.

It can also be configured by writing to the bit 5 of register 0x17 - RMII

When phydev->interface is rmii, rmii mode must be enabled, otherwise

Commit bb726b753f75 ("net: phy: realtek: add support for
RTL8211F(D)(I)-VD-CG") extended support of the driver from the existing
support for RTL8211F(D)(I)-CG PHY to the newer RTL8211F(D)(I)-VD-CG PHY.
While that commit indicated that the RTL8211F_PHYCR2 register is not
supported by the "VD-CG" PHY model and therefore updated the corresponding
section in rtl8211f_config_init() to be invoked conditionally, the call to
"genphy_soft_reset()" was left as-is, when it should have also been invoked
conditionally. This is because the call to "genphy_soft_reset()" was first
introduced by the commit 0a4355c2b7f8 ("net: phy: realtek: add dt property
to disable CLKOUT clock") since the RTL8211F guide indicates that a PHY
reset should be issued after setting bits in the PHYCR2 register.
As the PHYCR2 register is not applicable to the "VD-CG" PHY model, fix the
rtl8211f_config_init() function by invoking "genphy_soft_reset()"
conditionally based on the presence of the "PHYCR2" register.

Since commit d492cc2573a0 ("driver core: device.h: make struct
bus_type a const *"), the driver core can properly handle constant
struct bus_type, move the mdio_bus_type variable to be a constant
structure as well, placing it into read-only memory which can not be
modified at runtime.

Add Aquantia AQR111 and AQR111B0 PHY ID. These PHY advertise 10G speed
but actually supports up to 5G speed, hence some manual fixup is needed.
The Aquantia AQR111B0 PHY is just a variant of the AQR111 with smaller
chip size.

Currently, we are checking whether the PHY package mode matches the
individual PHY interface modes at PHY package probe time, but at that time
we only know the PHY package mode and not the individual PHY interface
modes as of_get_phy_mode() that populates it will only get called once the
netdev to which PHY-s are attached to is being probed and thus this check
will always fail and return -EINVAL.
So, lets move this check to .config_init_once as at that point individual
PHY interface modes should be populated.
