Subject: [PATCH net-next 0/2] ptp: add control over HW timestamp latch point
Date: Mon, 21 Oct 2024 16:19:53 +0200 [thread overview]
Message-ID: <20241021141955.1466979-1-arkadiusz.kubalewski@intel.com> (raw)
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.
