ethtool: move to its own directory The ethtool netlink interface is going to be split into multiple files so that it will be more convenient to put all of them in a separate directory net/ethtool. Start by moving current ethtool.c with ioctl interface into this directory and renaming it to ioctl.c.

ethtool: introduce ethtool netlink interface Basic genetlink and init infrastructure for the netlink interface, register genetlink family "ethtool". Add CONFIG_ETHTOOL_NETLINK Kconfig option to make the build optional. Add initial overall interface description into Documentation/networking/ethtool-netlink.rst, further patches will add more detailed information.

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 channel counts with CHANNELS_GET request Implement CHANNELS_GET request to get channel counts of a network device. These are traditionally available via ETHTOOL_GCHANNELS ioctl request. Omit attributes for channel types which are not supported by driver or device (zero reported for maximum). v2: (all suggested by Jakub Kicinski) - minor cleanup in channels_prepare_data() - more descriptive channels_reply_size() - omit attributes with zero max count Signed-off-by: Michal Kubecek <mkubecek@suse.cz> Reviewed-by: Jakub Kicinski <kuba@kernel.org> Signed-off-by: David S.

ethtool: add tunnel info interface Add an interface to report offloaded UDP ports via ethtool netlink. Now that core takes care of tracking which UDP tunnel ports the NICs are aware of we can quite easily export this information out to user space. The responsibility of writing the netlink dumps is split between ethtool code and udp_tunnel_nic.c - since udp_tunnel module may not always be loaded, yet we should always report the capabilities of the NIC. $ ethtool --show-tunnels eth0 Tunnel information for eth0: UDP port table 0: Size: 4 Types: vxlan No entries UDP port table 1: Size: 4 Types: geneve, vxlan-gpe Entries (1): port 1230, vxlan-gpe v4: - back to v2, build fix is now directly in udp_tunnel.h v3: - don't compile ETHTOOL_MSG_TUNNEL_INFO_GET in if CONFIG_INET not set. v2: - fix string set count, - reorder enums in the uAPI, - fix type of ETHTOOL_A_TUNNEL_UDP_TABLE_TYPES to bitset in docs and comments.

ethtool: add interface to interact with Ethernet Power Equipment Add interface to support Power Sourcing Equipment. At current step it provides generic way to address all variants of PSE devices as defined in IEEE 802.3-2018 but support only objects specified for IEEE 802.3-2018 104.4 PoDL Power Sourcing Equipment (PSE). Currently supported and mandatory objects are: IEEE 802.3-2018 30.15.1.1.3 aPoDLPSEPowerDetectionStatus IEEE 802.3-2018 30.15.1.1.2 aPoDLPSEAdminState IEEE 802.3-2018 30.15.1.2.1 acPoDLPSEAdminControl This is minimal interface needed to control PSE on each separate ethernet port but it provides not all mandatory objects specified in IEEE 802.3-2018. Since "PoDL PSE" and "PSE" have similar names, but some different values I decide to not merge them and keep separate naming schema. This should allow as to be as close to IEEE 802.3 spec as possible and avoid name conflicts in the future. This implementation is connected to PHYs instead of MACs because PSE auto classification can potentially interfere with PHY auto negotiation. So, may be some extra PHY related initialization will be needed. With WIP version of ethtools interaction with PSE capable link looks as following: $ ip l ... 5: t1l1@eth0: <BROADCAST,MULTICAST> .. ... $ ethtool --show-pse t1l1 PSE attributs for t1l1: PoDL PSE Admin State: disabled PoDL PSE Power Detection Status: disabled $ ethtool --set-pse t1l1 podl-pse-admin-control enable $ ethtool --show-pse t1l1 PSE attributs for t1l1: PoDL PSE Admin State: enabled PoDL PSE Power Detection Status: delivering power Signed-off-by: kernel test robot <lkp@intel.com> Signed-off-by: Oleksij Rempel <o.rempel@pengutronix.de> Reviewed-by: Bagas Sanjaya <bagasdotme@gmail.com> Reviewed-by: Andrew Lunn <andrew@lunn.ch> Signed-off-by: Jakub Kicinski <kuba@kernel.org>
