That would be helpful.

Hi Richard and Rodney,
I really appreciate all your helps.
The discussion makes me understand 802.1AS better, and work on it with more
confidence.
Now I have rebased the 4 patches for TAB on latest master branch.
I did tests with 3 NXP LS1043ARDB boards, to verify time-aware bridge working
as m
According to IEEE 802.1AS-2011, the BMCA used in gPTP is the same
as that used in IEEE 1588 with the following exceptions:
(1) Announce messages received on a slave port that were not sent
by the receiving time-aware system are used immediately,
i.e., there is no foreign-master qualification.
(2)

When a connected peer introduces a time discontinuities in between
consecutive peer-delay measurements (i.e. a jump in time in
consecutive PDelay response), an erroneous neighbor rate ratio is
calculated. This change disqualifies any neighbor rate ratio that
exceeds +/- 1

IEEE 802.1AS-2011's methodology for faults is to avoid waiting
in that FAULTY state in hopes that management will notice.
Instead, move on to search for a valid non-faulty state. If
supported, the fault is logged so that management can notice
later, but that logging isn't
This patch is to add IEEE 802.1AS-2011 time-aware bridge support
based on current BC clock type. It implements only time information
relay, and BMCA was not touched. To run it, the profile gPTP.cfg could
be used with multiple interfaces specified using -i option.
The main code changes are,
- Creat
This patch-set is to add IEEE 802.1AS-2011 time-aware bridge support.
The implementation is based on BC clock type. The main changes are,
- Support time information relay through follow_up_TLV.
- Support BMCA for IEEE 802.1AS-2011 time-aware bridge.
- Implement other difference of IEEE 802.1AS-2011
