From d6cf07327e691e8f7c0f08af69d0dd3887aa1e4f Mon Sep 17 00:00:00 2001 From: Richard Cochran <richardcochran@gmail.com> Date: Sun, 19 Jun 2011 21:51:27 +0000 Subject: [PATCH] fec_mpc52xx: enable transmit and receive time stamping. This patch enables software (and phy device) time stamping. Software time stamping using the SO_TIMESTAMPING API was tested and found to be working on the LITE5200B board.
