Add support for printing control messages containing software and/or hardware timestamps, which are typically enabled by NTP and PTP implementations. * print_timeval.c (print_struct_timeval_data_size): New mpers printer. * print_timespec.c (print_struct_timespec_data_size, print_struct_timespec_array_data_size): Likewise. * msghdr.c (print_scm_timestamp, print_scm_timestampns, print_scm_timestamping): New functions. (cmsg_socket_printers): Add them. * NEWS: Mention this change. * tests/msg_control.c: Include "xlat.h" and "xlat/scmvals.h". (test_scm_timestamp, test_scm_timestampns, test_scm_timestamping): New functions. (test_sol_socket): Use them. Signed-off-by: Miroslav Lichvar <mlichvar@redhat.com> Signed-off-by: Dmitry V.
