Implement TSINFO_GET request to get timestamping information for a network device. This is traditionally available via ETHTOOL_GET_TS_INFO ioctl request. Move part of ethtool_get_ts_info() into common.c so that ioctl and netlink code use the same logic to get timestamping information from the device. v3: use "TSINFO" rather than "TIMESTAMP", suggested by Richard Cochran Signed-off-by: Michal Kubecek <mkubecek@suse.cz> Acked-by: Richard Cochran <richardcochran@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
