This calculation is done using the timestamps but without any correction.

The 2 octets were displayed as as int16 so they can be swapped depending
of the architecture.

This field is used to store the active peer connected to an instance. In
wr_mon tool, it replaces the field peer on the display which was not
very explicit when many peers are connected on the same port. The field
activePeer takes the value of peer field in the following cases :

           MASTER          UNCALIBRATED/SLAVE
P2P     Rx PDELAY_RESP    Rx qualified ANNOUNCE
          (Filtered)
E2E       DELAY_RESP      Rx qualified ANNOUNCE

In other cases, the activePeer field is set to 0

The WR time is set in GM mode as follow :
1/ At startup the NTP time is set using wr_date script
2/ PPSi calls the tool wr_date with parameters "set host". It will be
called every time it detects a PLL transition from UNLOCKED to LOCKED
state. Also PPSi provide a error counter 'gmUnlockErr' which gives the
number of time the PLL unlocked.
3/ Parameters "-v set host" in wr_date tool, set only the second part of
the WR time. The time is set in a middle of two WR seconds ticks.

- Change the Quality structure to make it compliant with the standard
- Fix network to host conversion to display offsetScaledLogVariance

This tool is used to follow the value of a monotonic clock to check if
it does not does big jumps. This jumps may affect the precision of the
timeout in PPSi. They can occur when the nanosecond adjustement is done
in the servo (WR & HA profiles).

. Better integrate of code optimization with PPSi Kconfig
. PPSi Kconfig changes to simplify the code in PPSi and avoid #ifdef ..
. Improve code optimization
. Move some declaration in ppsi.h in other files to ligthen ppsi.h
. Improvement of timers: global or instance dependent, dyn. allocation,
renaming for better diagnostics, disabling allowed, ...
. New behaviour for the PPS output generation (configurable,...)
. Move control of the timing mode from HAL to PPSi
. Optimization of code when a Protocol extension is not available
. BMCA: Calculate the ebest,... only one time and then trigger all
instances to execute the bmca state descision
. Fix bug in the calculation of the clockIdentity to bring it into
compliance with PTP spec 2008 document
. Fix a bug related to Announce message received in SLAVE/UNCALIB
. WR ext: use dynamic timer and adapt to new PPS generation
. HA ext: Fix bug in fault injection mechanism

- New L1Sync and PTP servo calculation (delayAsym,...)
- Make function calls more uniforms between extensions
- refactoring
- Add a new state machine to enable/disable an extension and provide
only PTP support: New timer, new hooks, ...
- Fix bug in time format conversion
- Code removed when an extension is not required (#ifdef XXX )
- Align the PTP and L1Sync servo calculation (shared fct, same
calculation,...)
- Force only one servo running at a given time for a given instance
- New servo reset hook : called by main loop
- Add function to converte a time into a string
- Force to stay in FAULTY state during 60s
- Optimise function wrs_enable_timing_output()

- Update of portDs.meanLinkDelay for P2P mechanism
- Fix issue updating currentDS.meanDelay

When the extension L1SYNC is not available (no data), the value of
L1SyncEnable and L1SyncState are emulated and displayed. Some VERYX
tests need these information also when L1SYNC is disabled.

- When optParamsEnabled is set, the TLV send need to be extended with
extra values. Fix here the length of the TLV and the whole message.
- Fix print issue of the signaling TLV

When received frames are displayed (diagnostic mode), PPSI was staying
forever in a loop due to unexpected TLV received in the frame.

This implementation does not include yet the possibility to declare 2
exclusive instances on a same port (WR & HA)
- Some structures are renamed with the suffix _t to make it more
readable.
- Some variables are renamed  to be more clear
- Implementation of masterOnly, slaveOnly and externalPortConfiguration
- All extension specific includes (XX-api.h) is now automatically
included in ppsi.h and do not need to be included in other files.

- New  parameters added
- Parameter check with min/max values
- Updated fied mask suppressed: At startup the conf structure in each
ppsi instance must be initialized with the default values.

This implementation works on a WR Switch but does not yet integrate all
required functionalities. List of current modifications :
- Implementation of the L1SYNC protocol
- Modifications of the standard protocol: new hook, TS calculation
- Change WRS to integrate HA
- HAL adaptations

Compilation of wrs_dump_shmem_ppsi.c is done from the wr-switch-sw repo
since it needs wrs_dump_shmem.h, which is in wr-switch-sw repo.
I wanted to avoid keeping two copies of .h file.

Commit only build for arch-unix (and no tools either)
This simplifies a lot the calculations.

  - all times are now living in a single structure
  - all fields are signed and 64-bit long
  - the 2038 bug is over (we still had 32-bit seconds)
  - no overflow in math or unexplained "unsigned" appearing

Building with musl was spitting errors for redefined data structures.
Use the standard headers when available (I found not alternatives to
linux/if_packet.h, but it spits no error).

Then, ifr.ifr_data is "caddr_t" not "void *" in musl, so cast the
pointer being assigned to silent a warning.

Finally, the fields of udphdr in musl use different names unless wi
add _GNU_SOURCE -- most likely musl is more posixly-correct, I didn't check.

While looking for an alignment bug I had bad frames: being able to
look at the binary content of all ptp-ethtype frames (or ip/udp/ptp)
is very useful in that situation.
