ethtool: provide netdev features with FEATURES_GET request Implement FEATURES_GET request to get network device features. These are traditionally available via ETHTOOL_GFEATURES ioctl request. v2: - style cleanup suggested by Jakub Kicinski Signed-off-by: Michal Kubecek <mkubecek@suse.cz> Reviewed-by: Jakub Kicinski <kuba@kernel.org> Signed-off-by: David S. Miller <davem@davemloft.net>

ethtool: set netdev features with FEATURES_SET request Implement FEATURES_SET netlink request to set network device features. These are traditionally set using ETHTOOL_SFEATURES ioctl request. Actual change is subject to netdev_change_features() sanity checks so that it can differ from what was requested. Unlike with most other SET requests, in addition to error code and optional extack, kernel provides an optional reply message (ETHTOOL_MSG_FEATURES_SET_REPLY) in the same format but with different semantics: information about difference between user request and actual result and difference between old and new state of dev->features. This reply message can be suppressed by setting ETHTOOL_FLAG_OMIT_REPLY flag in request header. Signed-off-by: Michal Kubecek <mkubecek@suse.cz> Signed-off-by: David S. Miller <davem@davemloft.net>

ethtool: add FEATURES_NTF notification Send ETHTOOL_MSG_FEATURES_NTF notification whenever network device features are modified using ETHTOOL_MSG_FEATURES_SET netlink message, ethtool ioctl request or any other way resulting in call to netdev_update_features() or netdev_change_features() Signed-off-by: Michal Kubecek <mkubecek@suse.cz> Signed-off-by: David S.
