[Linuxptp-devel] [PATCH 00/13] Prepare for sub-nanosecond timestamps

2018-02-28 Thread Michael Brown
The following series of patches adds support required for sub-nanosecond timestamps in ptp4l. The kernel-to-userspace API data structures for reporting such timestamps are not yet defined, but this code is verified to achieve sub-nanosecond synchronisation over IPv6 (6LoWPAN) using a DecaWave DW10
