Up until now, there was no way to let the user select the hardware
PTP provider at which time stamping occurs. The stack assumed that PHY time
stamping is always preferred, but some MAC/PHY combinations were buggy.

This series updates the default MAC/PHY default timestamping and aims to
allow the user to select the desired hwtstamp provider administratively.

Changes in v10:
- Move declarations to net/core/dev.h instead of netdevice.h
- Add netlink documentation.
- Add ETHTOOL_A_TSINFO_GHWTSTAMP netlink attributes instead of a bit in
  ETHTOOL_A_TSINFO_TIMESTAMPING bitset.
- Send "Move from simple ida to xarray" patch standalone.
- Add tsinfo ntf command.
- Add rcu_lock protection mechanism to avoid memory leak.
- Fixed doc and kdoc issue.
- Link to v9: https://lore.kernel.org/r/20240226-feature_ptp_netnext-v9-0-455611549f21@bootlin.com

Changes in v9:
- Remove the RFC prefix.
- Correct few NIT fixes.
- Link to v8: https://lore.kernel.org/r/20240216-feature_ptp_netnext-v8-0-510f42f444fb@bootlin.com

Changes in v8:
- Drop the 6 first patch as they are now merged.
- Change the full implementation to not be based on the hwtstamp layer
  (MAC/PHY) but on the hwtstamp provider which mean a ptp clock and a
  phc qualifier.
- Made some patch to prepare the new implementation.
- Expand netlink tsinfo instead of a new ts command for new hwtstamp
  configuration uAPI and for dumping tsinfo of specific hwtstamp provider.
- Link to v7: https://lore.kernel.org/r/20231114-feature_ptp_netnext-v7-0-472e77951e40@bootlin.com

Changes in v7:
- Fix a temporary build error.
- Link to v6: https://lore.kernel.org/r/20231019-feature_ptp_netnext-v6-0-71affc27b0e5@bootlin.com

Changes in v6:
- Few fixes from the reviews.
- Replace the allowlist to default_timestamp flag to know which phy is
  using old API behavior.
- Rename the timestamping layer enum values.
- Move to a simple enum instead of the mix between enum and bitfield.
- Update ts_info and ts-set in software timestamping case.

Changes in v5:
- Update to ndo_hwstamp_get/set. This bring several new patches.
- Add few patches to make the glue.
- Convert macb to ndo_hwstamp_get/set.
- Add netlink specs description of new ethtool commands.
- Removed netdev notifier.
- Split the patches that expose the timestamping to userspace to separate
  the core and ethtool development.
- Add description of software timestamping.
- Convert PHYs hwtstamp callback to use kernel_hwtstamp_config.

Changes in v4:
- Move on to ethtool netlink instead of ioctl.
- Add a netdev notifier to allow packet trapping by the MAC in case of PHY
  time stamping.
- Add a PHY whitelist to not break the old PHY default time-stamping
  preference API.

Changes in v3:
- Expose the PTP choice to ethtool instead of sysfs.
  You can test it with the ethtool source on branch feature_ptp of:
  https://github.com/kmaincent/ethtool
- Added a devicetree binding to select the preferred timestamp.

Changes in v2:
- Move selected_timestamping_layer variable of the concerned patch.
- Use sysfs_streq instead of strmcmp.
- Use the PHY timestamp only if available.

Timestamping software or hardware flags are often used as a group,
therefore adding these masks will ease future use.

I did not use SOF_TIMESTAMPING_SYS_HARDWARE flag as it is deprecated and
not used at all.

This declaration was added to the header to be called from ethtool.
ethtool is separated from core for code organization but it is not really
a separate entity, it controls very core things.
As ethtool is an internal stuff it is not wise to have it in netdevice.h.
Move the declaration to net/core/dev.h instead.

Remove the EXPORT_SYMBOL_GPL call as ethtool can not be built as a module.

Change the API to select MAC default time stamping instead of the PHY.
Indeed the PHY is closer to the wire therefore theoretically it has less
delay than the MAC timestamping but the reality is different. Due to lower
time stamping clock frequency, latency in the MDIO bus and no PHC hardware
synchronization between different PHY, the PHY PTP is often less precise
than the MAC. The exception is for PHY designed specially for PTP case but
these devices are not very widespread. For not breaking the compatibility
default_timestamp flag has been introduced in phy_device that is set by
the phy driver to know we are using the old API behavior.

Changes in v5:
- Extract the API change in this patch.
- Rename whitelist to allowlist.
- Set NETDEV_TIMESTAMPING in register_netdevice function.
- Add software timestamping case description in ts_info.

Change in v6:
- Replace the allowlist phy with a default_timestamp flag to know which
  phy is using old API behavior.
- Fix dereferenced of a possible null pointer.
- Follow timestamping layer naming update.
- Update timestamp default set between MAC and software.
- Update ts_info returned in case of software timestamping.

Change in v8:
- Reform the implementation to use a simple phy_is_default_hwtstamp helper
  instead of saving the hwtstamp in the net_device struct.

Change in v9:
- Update few nit following the review.

Prepare for future support of saving hwtstamp source in PTP xarray by
introducing HWTSTAMP_SOURCE_UNSPEC to hwtstamp_source enum, setting it
to 0 to match old behavior of no source defined.

In prevision to add new UAPI for hwtstamp we will be limited to the struct
ethtool_ts_info that is currently passed in fixed binary format through the
ETHTOOL_GET_TS_INFO ethtool ioctl. It would be good if new kernel code
already started operating on an extensible kernel variant of that
structure, similar in concept to struct kernel_hwtstamp_config vs struct
hwtstamp_config.

Since struct ethtool_ts_info is in include/uapi/linux/ethtool.h, here
we introduce the kernel-only structure in include/linux/ethtool.h.
The manual copy is then made in the function called by ETHTOOL_GET_TS_INFO.

Prepare for future hardware timestamp selection by adding source and
corresponding pointers to ptp_clock structure. Additionally, introduce
helpers for registering specific phydev or netdev PTP clocks, retrieving
PTP clock information such as hwtstamp source or phydev/netdev pointers,
and obtaining the ptp_clock structure from the phc index.

Change in v8:
- New patch.

Change in v10:
- Add get and put function to avoid unregistering a ptp clock object used.
- Fix kdoc issues.

Introduce the description of a hwtstamp provider which is define with a
ptp_clock pointer and a qualifier value.

Add a hwtstamp provider description within the netdev structure to be able
to select the hwtstamp we want too use. By default we use the old API that
does not support hwtstamp selectability which mean the hwtstamp ptp_clock
pointer is unset.

Change in v8:
- New patch

Change in v10:
- Set hwtstamp in netdevice as a pointer for future use of rcu lock.
- Fix a nit in teh order of setting phydev pointer.
- Add a missing kdoc description.

The hardware registration clock for net device is now using
netdev_ptp_clock_register to save the net_device pointer within the PTP
clock xarray. netdevsim is registering its ptp through the mock driver.
It is the only driver using the mock driver to register a ptp clock.
Convert the mock driver to the new API.

Enhance 'get' command to retrieve tsinfo of hwtstamp providers within a
network topology and read current hwtstamp configuration.

Introduce support for ETHTOOL_MSG_TSINFO_SET ethtool netlink socket to
configure hwtstamp of a PHC provider. Note that simultaneous hwtstamp
isn't supported; configuring a new one disables the previous setting.

Also, add support for a specific dump command to retrieve all hwtstamp
providers within the network topology, with added functionality for
filtered dump to target a single interface.

Pointer attached_dev is used to know if the phy is on the net topology.
This might not be enough and might need Maxime Chevallier link topology

Add new attributed to tsinfo allowing to get the tsinfo and the hwtstamp
from a phc provider (composed by a phc index and a phc qualifier) on a
netdevice's link.
Add simultaneously a set command to be able to set hwtstamp configuration
for a specified phc provider.

At this point this function does not need to be defined in a header at
all. But patch 12 will change that.

net/ethtool can be built-in or not, but cannot be built as module, so
no need for the EXPORT_SYMBOL_GPL indeed.

Given that this path corresponds to the driver I wrote, do I assume
that you've picked up my work on PTP support for Marvell PHYs? You
should be aware that I still have the patches out of tree but it's
been pointless me reposting it until the issue of which PTP gets
used has been solved. (Publishing will just increase the pressure
to merge it without the PTP problems being solved, and thus break
Marvell PP2 PTP.)

Yes I did with few fixes and I know you don't want to post the patches until
setting which PTP gets used has been solved. As you can see this is one of the
subject of this series. About it, could you review this series? This would help
a lot and you will be able to post again your Marvell PTP patches if its get
merged.

I wish I could, but I'm seriously short of available time at the
moment. I'm fitting in what I can day by day and there are many
things wanting my attention - but I don't have enough time at the
moment for everything. So really I can't take on anything new
right now.

IMHO these four helpers just add a layer of indirection without much
benefit.

Do we ever expect more than two sources? Else, the phc_source could be
embedded as the least significant bit of the pointer in the union. In
that case we would need helpers to return the pointer without that LSB.
But space in struct ptp_clock is probably not so valuable that we need
to play such games.

No need for explicit extern?

Actually, ignore this. This is not important enough to revise when
we're alredy at v10. That also goes for the other points.

Indeed I don't think it is needed.
I am wondering why few other functions uses it (ptp_clock_register,
ptp_clock_event, ptp_clock_index). Do you know?
