└─>Intel PCH EG20T as PTP clock
In linux kernel since version 3.1 (release Date: 2011-10-24)
This driver adds support for using the PCH EG20T as a PTP
clock. The hardware supports time stamping of PTP packets
when using the end-to-end delay (E2E) mechanism. The peer
delay mechanism (P2P) is not supported.
This clock is only useful if your PTP programs are getting
hardware time stamps on the PTP Ethernet packets using the
SO_TIMESTAMPING API.
To compile this driver as a module, choose M here: the module
will be called ptp_pch.
