[Linuxptp-devel] Driver Support Matrix Additions

[Chris Healy]

Intel recently (01/10/13) added HW time stamping support for their e1000e
driver stack. This was upstreamed a few days ago.

e1000e: add support for hardware timestamping on some devices

On 82574, 82583, 82579, I217 and I218 add support for hardware time
stamping of all or no Rx packets and Tx packets which have the
SKBTX_HW_TSTAMP flag set. Update the .get_ts_info ethtool operation to
report the supported time stamping modes, and enable and disable hardware
time stamping with the SIOCSHWTSTAMP ioctl.


I have not tested with this yet, but the driver support matrix should
probably be updated to reflect this change.

Thanks for the reminder. The second patch (with PHC support) is going
to be resubmitted, I hope, so I'll hold off until that one gets merged
into net-next.

Thanks,

Freescale recently added time stamping support to their FEC driver when
running on Freescale i.MX6 platforms.

FEC: Add time stamping code and a PTP hardware clock

This patch adds a driver for the FEC(MX6) that offers time
stamping and a PTP haderware clock. Because FEC\ENET(MX6)
hardware frequency adjustment is complex, we have implemented
this in software by changing the multiplication factor of the
timecounter.
