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.

net: hsr: add offloading support Add support for offloading of HSR/PRP (IEC 62439-3) tag insertion tag removal, duplicate generation and forwarding. For HSR, insertion involves the switch adding a 6 byte HSR header after the 14 byte Ethernet header. For PRP it adds a 6 byte trailer. Tag removal involves automatically stripping the HSR/PRP header/trailer in the switch. This is possible when the switch also performs auto deduplication using the HSR/PRP header/trailer (making it no longer required). Forwarding involves automatically forwarding between redundant ports in an HSR. This is crucial because delay is accumulated as a frame passes through each node in the ring. Duplication involves the switch automatically sending a single frame from the CPU port to both redundant ports. This is required because the inserted HSR/PRP header/trailer must contain the same sequence number on the frames sent out both redundant ports. Export is_hsr_master so DSA can tell them apart from other devices in dsa_slave_changeupper.

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.

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.

net: ethtool: require drivers to set supported_coalesce_params Now that all in-tree drivers have been updated we can make the supported_coalesce_params mandatory. To save debugging time in case some driver was missed (or is out of tree) add a warning when netdev is registered with set_coalesce but without supported_coalesce_params.

ethtool: provide timestamping information with TSINFO_GET request 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.

ethtool: Remove link_mode param and derive link params from driver Some drivers clear the 'ethtool_link_ksettings' struct in their get_link_ksettings() callback, before populating it with actual values. Such drivers will set the new 'link_mode' field to zero, resulting in user space receiving wrong link mode information given that zero is a valid value for the field. Another problem is that some drivers (notably tun) can report random values in the 'link_mode' field. This can result in a general protection fault when the field is used as an index to the 'link_mode_params' array [1]. This happens because such drivers implement their set_link_ksettings() callback by simply overwriting their private copy of 'ethtool_link_ksettings' struct with the one they get from the stack, which is not always properly initialized. Fix these problems by removing 'link_mode' from 'ethtool_link_ksettings' and instead have drivers call ethtool_params_from_link_mode() with the current link mode. The function will derive the link parameters (e.g., speed) from the link mode and fill them in the 'ethtool_link_ksettings' struct. v3: * Remove link_mode parameter and derive the link parameters in the driver instead of passing link_mode parameter to ethtool and derive it there. v2: * Introduce 'cap_link_mode_supported' instead of adding a validity field to 'ethtool_link_ksettings' struct.
