====================
ptp: Support hardware clocks with additional free running cycle counter

ptp vclocks require a clock with free running time for the timecounter.
Currently only a physical clock forced to free running is supported.
If vclocks are used, then the physical clock cannot be synchronized
anymore. The synchronized time is not available in hardware in this
case. As a result, timed transmission with TAPRIO hardware support
is not possible anymore.

If hardware would support a free running time additionally to the
physical clock, then the physical clock does not need to be forced to
free running. Thus, the physical clocks can still be synchronized while
vclocks are in use.

The physical clock could be used to synchronize the time domain of the
TSN network and trigger TAPRIO. In parallel vclocks can be used to
synchronize other time domains.

One year ago I thought for two time domains within a TSN network also
two physical clocks are required. This would lead to new kernel
interfaces for asking for the second clock, ... . But actually for a
time triggered system like TSN there can be only one time domain that
controls the system itself. All other time domains belong to other
layers, but not to the time triggered system itself. So other time
domains can be based on a free running counter if similar mechanisms
like 2 step synchroisation are used.

Synchronisation was tested with two time domains between two directly
connected hosts. Each host run two ptp4l instances, the first used the
physical clock and the second used the virtual clock. I used my FPGA
based network controller as network device. ptp4l was used in
combination with the virtual clock support patches from Miroslav
Lichvar.

If a physical clock supports a free running cycle counter, then
timestamps shall be based on this time too. For TX it is known in
advance before the transmission if a timestamp based on the free running
cycle counter is needed. For RX it is impossible to know which timestamp
is needed before the packet is received and assigned to a socket.

Support late timestamp determination by a network device. Therefore, an
address/cookie is stored within the new netdev_data field of struct
skb_shared_hwtstamps. This address/cookie is provided to a new network
device function called ndo_get_tstamp(), which returns a timestamp based
on the normal/adjustable time or based on the free running cycle
counter. If function is not supported, then timestamp handling is not
changed.

This mechanism is intended for RX, but TX use is also possible.

100GbE Intel Wired LAN Driver Updates 2022-05-06

Marcin Szycik says:

This patchset adds support for systemd defined naming scheme for port
representors, as well as re-enables displaying PCI bus-info in ethtool.

bus-info information has previously been removed from ethtool for port
representors, as a workaround for a bug in lshw tool, where the tool would
sometimes display wrong descriptions for port representors/PF. Now the bug
has been fixed in lshw tool [1].

Removing the workaround can be considered a regression (user might be
running an older, unpatched version of lshw) (see [2] for discussion).
However, calling SET_NETDEV_DEV also produces the same effect as removing
the workaround, i.e. lshw is able to access PCI bus-info (this time not
via ethtool, but in some other way) and the bug can occur.

Adding SET_NETDEV_DEV is important, as it greatly improves netdev naming -
- port representors are named based on PF name. Currently port representors
are named "ethX", which might be confusing, especially when spawning VFs on
multiple PFs. Furthermore, it's currently harder to determine to which PF
does a particular port representor belong, as bus-info is not shown in
ethtool.

Consider the following three cases:

Case 1: current code - driver workaround in place, no SET_NETDEV_DEV,
lshw with or without fix. Port representors are not displayed because they
don't have bus-info (the workaround), PFs are labelled correctly:

$ sudo ./lshw -c net -businfo
Bus info          Device      Class          Description
========================================================
pci@0000:02:00.0  ens6f0      network        Ethernet Controller E810-XXV for SFP <-- PF
pci@0000:02:00.1  ens6f1      network        Ethernet Controller E810-XXV for SFP
pci@0000:02:01.0  ens6f0v0    network        Ethernet Adaptive Virtual Function <-- VF
pci@0000:02:01.1  ens6f0v1    network        Ethernet Adaptive Virtual Function
...

Case 2: driver workaround in place, SET_NETDEV_DEV, no lshw fix. Port
representors have predictable names. lshw is able to get bus-info because
of SET_NETDEV_DEV and netdevs CAN be mislabelled:

$ sudo ./lshw -c net -businfo
Bus info          Device           Class          Description
=============================================================
pci@0000:02:00.0  ens6f0npf0vf60   network        Ethernet Controller E810-XXV for SFP <-- mislabeled port representor
pci@0000:02:00.1  ens6f1           network        Ethernet Controller E810-XXV for SFP
pci@0000:02:01.0  ens6f0v0         network        Ethernet Adaptive Virtual Function
pci@0000:02:01.1  ens6f0v1         network        Ethernet Adaptive Virtual Function
...
pci@0000:02:00.0  ens6f0npf0vf26   network        Ethernet interface
pci@0000:02:00.0  ens6f0           network        Ethernet interface <-- mislabeled PF
pci@0000:02:00.0  ens6f0npf0vf81   network        Ethernet interface
...
$ sudo ethtool -i ens6f0npf0vf60
driver: ice
...
bus-info:
...

Output of lshw would be the same with workaround removed; it does not
change the fact that lshw labels netdevs incorrectly, while at the same
time it prevents ethtool from displaying potentially useful data
(bus-info).

Case 3: workaround removed, SET_NETDEV_DEV, lshw fix:

$ sudo ./lshw -c net -businfo
Bus info          Device           Class          Description
=============================================================
pci@0000:02:00.0  ens6f0npf0vf73   network        Ethernet Controller E810-XXV for SFP
pci@0000:02:00.1  ens6f1           network        Ethernet Controller E810-XXV for SFP
pci@0000:02:01.0  ens6f0v0         network        Ethernet Adaptive Virtual Function
pci@0000:02:01.1  ens6f0v1         network        Ethernet Adaptive Virtual Function
...
pci@0000:02:00.0  ens6f0npf0vf5    network        Ethernet Controller E810-XXV for SFP
pci@0000:02:00.0  ens6f0           network        Ethernet Controller E810-XXV for SFP
pci@0000:02:00.0  ens6f0npf0vf60   network        Ethernet Controller E810-XXV for SFP
...
$ sudo ethtool -i ens6f0npf0vf73
driver: ice
...
bus-info: 0000:02:00.0
...

In this case poort representors have predictable names, netdevs are not
mislabelled in lshw, and bus-info is shown in ethtool.
