ethtool: provide link state with LINKSTATE_GET request Implement LINKSTATE_GET netlink request to get link state information. At the moment, only link up flag as provided by ETHTOOL_GLINK ioctl command is returned. LINKSTATE_GET request can be used with NLM_F_DUMP (without device identification) to request the information for all devices in current network namespace providing the data.

ethtool: provide link mode names as a string set Unlike e.g. netdev features, the ethtool ioctl interface requires link mode table to be in sync between kernel and userspace for userspace to be able to display and set all link modes supported by kernel. The way arbitrary length bitsets are implemented in netlink interface, this will be no longer needed. To allow userspace to access all link modes running kernel supports, add table of ethernet link mode names and make it available as a string set to userspace GET_STRSET requests. Add build time check to make sure names are defined for all modes declared in enum ethtool_link_mode_bit_indices. Once the string set is available, make it also accessible via ioctl.

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: set device channel counts with CHANNELS_SET request Implement CHANNELS_SET netlink request to set channel counts of a network device. These are traditionally set with ETHTOOL_SCHANNELS ioctl request. Like the ioctl implementation, the generic ethtool code checks if supplied values do not exceed driver defined limits; if they do, first offending attribute is reported using extack. Checks preventing removing channels used for RX indirection table or zerocopy AF_XDP socket are also implemented. Move ethtool_get_max_rxfh_channel() helper into common.c so that it can be used by both ioctl and netlink code. v2: - fix netdev reference leak in error path (found by Jakub Kicinsky) Signed-off-by: Michal Kubecek <mkubecek@suse.cz> Reviewed-by: Jakub Kicinski <kuba@kernel.org> Signed-off-by: David S.
