Subject: [PATCH] NET : Introduce SIOCGSTAMPNS ioctl to get timestamps with nanosec resolution

Hi David

This patch is for net-2.6.22 git tree.

A separate patch will follow for  SO_TIMESTAMPNS / SCM_TIMESTAMPNS support.

Thank you

[PATCH] 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.
