Thank you

[PATCH] NET : Adding SO_TIMESTAMPNS / SCM_TIMESTAMPNS support

Now that network timestamps use ktime_t infrastructure, we can add a new 
SOL_SOCKET sockopt  SO_TIMESTAMPNS.

This command is similar to SO_TIMESTAMP, but permits transmission of 
a 'timespec struct' instead of a 'timeval struct' control message. 
(nanosecond resolution instead of microsecond)

Control message is labelled SCM_TIMESTAMPNS instead of SCM_TIMESTAMP

A socket cannot mix SO_TIMESTAMP and SO_TIMESTAMPNS : the two modes are 
mutually exclusive.

sock_recv_timestamp() became too big to be fully inlined so I added a 
__sock_recv_timestamp() helper function.
