Background:

1. CONFIG_NCSI_OEM_CMD_KEEP_PHY

If this is enabled, we send an extra OEM Intel command in the probe
sequence immediately after discovering a channel (e.g. after "Clear
Initial State").

2. CONFIG_NCSI_OEM_CMD_GET_MAC

If this is enabled, we send one of 3 OEM "Get MAC Address" commands from
Broadcom, Mellanox (Nvidida), and Intel in the *configuration* sequence
for a channel.

3. mellanox,multi-host (or mlx,multi-host)

Introduced by this patch:

https://lore.kernel.org/all/20200108234341.2590674-1-vijaykhemka@fb.com/

Which was actually originally from cosmo.chou@quantatw.com:

https://github.com/facebook/openbmc-linux/commit/9f132a10ec48db84613519258cd8a317fb9c8f1b

Cosmo claimed that the Nvidia ConnectX-4 and ConnectX-6 NIC's don't
respond to Get Version ID, et. al in the probe sequence unless you send
the Set MC Affinity command first.

Problem Statement:

We've been using a combination of #ifdef code blocks and IS_ENABLED()
conditions to conditionally send these OEM commands.

It makes adding any new code around these commands hard to understand.

Solution:

In this patch, I just want to remove the conditionally compiled blocks
of code, and always use IS_ENABLED(...) to do dynamic control flow.

I don't think the small amount of code this adds to non-users of the OEM
Kconfigs is a big deal.

net: Make timestamping selectable

Up until now, there was no way to let the user select the layer 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 layer administratively.

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.

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

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 I
introduce a default_timestamp flag in phy_device that is set by the phy
driver to know we are using the old API behavior.

The phy_set_timestamp function is called at each call of phy_attach_direct.
In case of MAC driver using phylink this function is called when the
interface is turned up. Then if the interface goes down and up again the
last choice of timestamp will be overwritten by the default choice.
A solution could be to cache the timestamp status but it can bring other
issues. In case of SFP, if we change the module, it doesn't make sense to
blindly re-set the timestamp back to PHY, if the new module has a PHY with
mediocre timestamping capabilities.

                 Since these Unreachable messages indicate soft error

As mentioned in the TC Workshop 0x17, our recent changes to tdc broke
downstream CI systems like tuxsuite. The issue is the classic problem
with rcu/workqueue objects where you can miss them if not enough wall time
has passed. The latter is subjective to the system and kernel config,
in my machine could be nanoseconds while in another could be microseconds
or more.

In order to make the suite deterministic, poll for the existence
of the objects in a reasonable manner. Talking netlink directly is the
the best solution in order to avoid paying the cost of multiple
'fork()' calls, so introduce a netlink based setup routine using
pyroute2. We leave the iproute2 one as a fallback when pyroute2 is not
available.

Also rework the iproute2 side to mimic the netlink routine where it
creates DEV0 as the peer of DEV1 and moves DEV1 into the net namespace.
This way when the namespace is deleted DEV0 is also deleted
automatically, leaving no margin for resource leaks.

Another bonus of this change is that our setup time sped up by a factor
of 2 when using netlink.

This patch adds support for loading the firmware via MDIO as in most cases
there is no SPI-NOR being used to save on cost.
Firmware loading code itself is ported from mainline U-boot with cleanups.

The firmware has mixed values both in big and little endian.
PHY core itself is big-endian but it expects values to be in little-endian.
The firmware is little-endian but CRC-16 value for it is stored at the end
of firmware in big-endian.

It seems the PHY does the conversion internally from firmware that is
little-endian to the PHY that is big-endian on using the mailbox
but mailbox returns a big-endian CRC-16 to verify the written data
