linux-toradex.git/include/linux/ptp_classify.h, branch v3.0-rc3 Linux kernel for Apalis and Colibri modules ptp: Added a brand new class driver for ptp clocks. 2011-05-23T20:01:00+00:00 Richard Cochran richardcochran@gmail.com 2011-04-22T10:03:08+00:00 d94ba80ebbea17f036cecb104398fbcd788aa742 This patch adds an infrastructure for hardware clocks that implement IEEE 1588, the Precision Time Protocol (PTP). A class driver offers a registration method to particular hardware clock drivers. Each clock is presented as a standard POSIX clock. The ancillary clock features are exposed in two different ways, via the sysfs and by a character device.

net: added a BPF to help drivers detect PTP packets. 2010-07-19T02:15:26+00:00 Richard Cochran richardcochran@gmail.com 2010-07-17T08:49:17+00:00 15f0127d1d189fda3294b7823e3e654afca54055 Certain kinds of hardware time stamping units in both MACs and PHYs have the limitation that they can only time stamp PTP packets. Drivers for such hardware are left with the task of correctly matching skbs to time stamps. This patch adds a BPF that drivers can use to classify PTP packets when needed.
