tcp: rename tcp_time_stamp() to tcp_time_stamp_ts()
This helper returns a TSval from a TCP socket. It currently calls tcp_time_stamp_ms() but will soon be able to return a usec based TSval, depending on an upcoming tp->tcp_usec_ts field. Signed-off-by: Eric Dumazet <edumazet@google.com> Signed-off-by: David S. Miller <davem@davemloft.net>
