From ae40eb1ef30ab4120bd3c8b7e3da99ee53d27a23 Mon Sep 17 00:00:00 2001 From: Eric Dumazet Date: Sun, 18 Mar 2007 17:33:16 -0700 Subject: [NET]: Introduce SIOCGSTAMPNS ioctl to get timestamps with nanosec resolution Now network timestamps use ktime_t infrastructure, we can add a new ioctl() SIOCGSTAMPNS command to get timestamps in 'struct timespec'. User programs can thus access to nanosecond resolution. Signed-off-by: Eric Dumazet CC: Stephen Hemminger Signed-off-by: David S.
