[Linuxptp-devel] [PATCH V3 0/9] Transparent Clock - third and final part

[Richard C. <ric...@gm...>]

This series adds support for running a TC over multiple ports.

Comments, testing, and review are most welcome.

Changed in V3:
~~~~~~~~~~~~~~

- Correct the behavior of the E2E TC with respect to the free_running
  option.  Now the E2E TC will synchronize when not free running, just
  like the P2P TC and the BC.  In this case, the TC will generate
  delay request messages.

- Pay attention to the domain field when synchronizing the local clock.

Changed in V2:
~~~~~~~~~~~~~~

- Detect and drop frames that arrive with time stamps.
- Add an option to enforce a spanning tree to avoid PTP message loops. 
- Set priority1 really low in the example TC configuration files

Thanks,
Richard
