From 92f37fd2ee805aa77925c1e64fd56088b46094fc Mon Sep 17 00:00:00 2001 From: Eric Dumazet Date: Sun, 25 Mar 2007 22:14:49 -0700 Subject: [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.
