[RFC PATCH 0/2] ptp: add control over HW timestamp latch point

[Arkadiusz Kubalewski]

HW support of PTP/timesync solutions in network PHY chips can be
achieved with two different approaches, the timestamp maybe latched
either in the beginning or after the Start of Frame Delimiter (SFD) [1].

Allow ptp device drivers to provide user with control over the timestamp
latch point.
