KSZ8061 needs to write to a MMD register at driver initialization to fix
an errata. This worked in 5.0 kernel but not in newer kernels. The
issue is the main phylib code no longer resets PHY at the very beginning.
Calling phy resuming code later will reset the chip if it is already
powered down at the beginning. This wipes out the MMD register write.
Solution is to implement a phy resume function for KSZ8061 to take care
of this problem.

When the PHY is powered up after powered down most of the registers are
reset, so the PHY setup code needs to be done again. In addition the

When the interrupt is enabled, the function lan8841_config_intr tries to
clear any pending interrupts by reading the interrupt status, then
checks the return value for errors and then continue to enable the
interrupt. It has been seen that once the system gets out of sleep mode,
the interrupt status has the value 0x400 meaning that the PHY detected
that the link was in low power. That is correct value but the problem is
that the check is wrong. We try to check for errors but we return an
error also in this case which is not an error. Therefore fix this by
returning only when there is an error.

The blamed commit started to use the ptp workqueue to get the second
part of the timestamp. And when the port was set down, then this
workqueue is stopped. But if the config option NETWORK_PHY_TIMESTAMPING
is not enabled, then the ptp_clock is not initialized so then it would
crash when it would try to access the delayed work.
So then basically by setting up and then down the port, it would crash.
The fix consists in checking if the ptp_clock is initialized and only
then cancel the delayed work.

The embedded PHYs of the 88E6250 family switches are very basic - they
do not even have an Extended Address / Page register.
This adds support for the PHYs to the driver to set up PHY interrupts
and retrieve error stats. To deal with PHYs without a page register,
"simple" variants of all stat handling functions are introduced.
The code should work with all 88E6250 family switches (6250/6220/6071/
6070/6020). The PHY ID 0x01410db0 was read from a 88E6020, under the
assumption that all switches of this family use the same ID. The spec
only lists the prefix 0x01410c00 and leaves the last 10 bits as reserved,
but that seems too unspecific to be useful, as it would cover several
existing PHY IDs already supported by the driver; therefore, the ID read
from the actual hardware is used.

Extend the PTP programmable gpios to implement also PTP_PF_EXTTS
function. The pins can be configured to capture both of rising
and falling edge. Once the event is seen, then an interrupt is
generated and the LTC is saved in the registers.
On lan8814 only GPIO 3 can be configured for this.
This was tested using:
ts2phc -m -l 7 -s generic -f ts2phc.cfg
Where the configuration was the following:
---
[global]
ts2phc.pin_index 3

Enhance the quirk for Fibrestore 2.5G copper SFP module. The original
commit e27aca3760c0 ("net: sfp: add quirk for FS's 2.5G copper SFP")
introducing the quirk says that the PHY is inaccessible, but that is
not true.
The module uses Rollball protocol to talk to the PHY, and needs a 4
second wait before probing it, same as FS 10G module.
The PHY inside the module is Realtek RTL8221B-VB-CG PHY. The realtek
driver recently gained support to set it up via clause 45 accesses.

Otherwise, if both LEDs are in use to indicate different speeds, the

Also make sure that state left behind by reset or the bootloader is

at reset. The driver explicitly disables WOL in config_init callback
which is called during init and during resume from suspend. Hence,
WOL is unconditionally disabled during resume, even if it was enabled
before the suspend. We make sure that WOL configuration is persistent

Lan8814 has 24 GPIOs but only 2 GPIOs (GPIO 0 and GPIO 1) can be
configured to generate period signals. And there are 2 events (EVENT_A
and EVENT_B) but these events are hardcoded to the GPIO 0 and GPIO 1.
These events are used to generate period signals. It is possible to
configure the length, the start time and the period of the signal by
configuring the event.
These events are generated by comparing the target time with the PHC
time. In case the PHC time is changed to a value bigger than the target
time + reload time, then it would generate only 1 event and then it
would stop because target time + reload time is smaller than PHC time.
Therefore it is required to change also the target time every time when
the PHC is changed. The same will apply also when the PHC time is
changed to a smaller value.
This was tested using:
testptp -i 1 -L 1,2
testptp -i 1 -p 1000000000 -w 200000000

The LTC for lan8814 was enabled only if timestamping was enabled,
otherwise it would be stopped. Meaning that LTC will not increase by
itself. This might break other features that don't required timestamping
like generating 1PPS. Therefore enable the LTC at probe time.

There are a few PHY drivers that can handle SFP modules through their
sfp_upstream_ops. Introduce Phylib helpers to keep track of connected
SFP PHYs in a netdevice's namespace, by adding the SFP PHY to the
upstream PHY's netdev's namespace.
By doing so, these SFP PHYs can be enumerated and exposed to users,
which will be able to use their capabilities.

Link topologies containing multiple network PHYs attached to the same
net_device can be found when using a PHY as a media converter for use
with an SFP connector, on which an SFP transceiver containing a PHY can
be used.
With the current model, the transceiver's PHY can't be used for
operations such as cable testing, timestamping, macsec offload, etc.
The reason being that most of the logic for these configuration, coming
from either ethtool netlink or ioctls tend to use netdev->phydev, which
in multi-phy systems will reference the PHY closest to the MAC.
Introduce a numbering scheme allowing to enumerate PHY devices that
belong to any netdev, which can in turn allow userspace to take more
precise decisions with regard to each PHY's configuration.
The numbering is maintained per-netdev, in a phy_device_list.
The numbering works similarly to a netdevice's ifindex, with
identifiers that are only recycled once INT_MAX has been reached.
This prevents races that could occur between PHY listing and SFP
transceiver removal/insertion.
The identifiers are assigned at phy_attach time, as the numbering
depends on the netdevice the phy is attached to. The PHY index can be
re-used for PHYs that are persistent.

The same implementation is also valid for 88E1145. VCT in 88E1111 is
similar to the 88E609x family. The main difference lies in register
organization and required workarounds.
It utilizes the same fields in registers but requires a simpler
implementation.

This commit implements VCT in 88E308X/88E609X Family.
It require two workarounds with some magic configuration.
Regular use require only one register configuration. But Open Circuit
require second workaround.
It cause implementation two phases for fault length measuring.
Fast Ethernet PHY have implemented very simple version of VCT. It's
complitley different than vct5 or vct7.

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.
