From e3aac889c78ab87de40a90cbb5fc0ff56394f47c Mon Sep 17 00:00:00 2001 From: Jacob Keller Date: Fri, 4 May 2012 02:56:12 +0000 Subject: [PATCH] ixgbe: add support for get_ts_info This patch adds support for the ethtool get_ts_info operation, which enables access of available timestamp/timesync support for that device. It can query which ptp clock device is associated with the particular port.
