ethtool: provide string sets with STRSET_GET request Requests a contents of one or more string sets, i.e. indexed arrays of strings; this information is provided by ETHTOOL_GSSET_INFO and ETHTOOL_GSTRINGS commands of ioctl interface. Unlike ioctl interface, all information can be retrieved with one request and mulitple string sets can be requested at once. There are three types of requests: - no NLM_F_DUMP, no device: get "global" stringsets - no NLM_F_DUMP, with device: get string sets related to the device - NLM_F_DUMP, no device: get device related string sets for all devices Client can request either all string sets of given type (global or device related) or only specific sets. With ETHTOOL_A_STRSET_COUNTS flag set, only set sizes (numbers of strings) are returned.

ethtool: provide message mask with DEBUG_GET request Implement DEBUG_GET request to get debugging settings for a device. At the moment, only message mask corresponding to message level as reported by ETHTOOL_GMSGLVL ioctl request is provided. (It is called message level in ioctl interface but almost all drivers interpret it as a bit mask.) As part of the implementation, provide symbolic names for message mask bits as ETH_SS_MSG_CLASSES string set.

ethtool: provide WoL settings with WOL_GET request Implement WOL_GET request to get wake-on-lan settings for a device, traditionally available via ETHTOOL_GWOL ioctl request. As part of the implementation, provide symbolic names for wake-on-line modes as ETH_SS_WOL_MODES string set.

ethtool: add timestamping related string sets Add three string sets related to timestamping information: ETH_SS_SOF_TIMESTAMPING: SOF_TIMESTAMPING_* flags ETH_SS_TS_TX_TYPES: timestamping Tx types ETH_SS_TS_RX_FILTERS: timestamping Rx filters These will be used for TIMESTAMP_GET request. v2: avoid compiler warning ("enumeration value not handled in switch") in net_hwtstamp_validate() v3: omit dash in Tx type names ("one-step-*" -> "onestep-*"), suggested by Richard Cochran Signed-off-by: Michal Kubecek <mkubecek@suse.cz> Acked-by: Richard Cochran <richardcochran@gmail.com> Signed-off-by: David S.
