2021-04-19ethtool: add missing EEPROM to list of messagesJakub Kicinski
ETHTOOL_MSG_MODULE_EEPROM_GET is missing from the list of messages. ETHTOOL_MSG_MODULE_EEPROM_GET_REPLY is sadly a rather long name so we need to adjust column length. v2: use spaces (Andrew) Fixes: c781ff12a2f3 ("ethtool: Allow network drivers to dump arbitrary EEPROM data") Signed-off-by: Jakub Kicinski <kuba@kernel.org> Signed-off-by: David S.

2021-04-15ethtool: add FEC statisticsJakub Kicinski
Similarly to pause statistics add stats for FEC. The IEEE standard mandates two sets of counters: - 30.5.1.1.17 aFECCorrectedBlocks - 30.5.1.1.18 aFECUncorrectableBlocks where block is a block of bits FEC operates on. Each of these counters is defined per lane (PCS instance). Multiple vendors provide number of corrected _bits_ rather than/as well as blocks. This set adds the 2 standard-based block counters and a extra one for corrected bits. Counters are exposed to user space via netlink in new attributes. Each attribute carries an array of u64s, first element is the total count, and the following ones are a per-lane break down. Much like with pause stats the operation will not fail when driver does not implement the get_fec_stats callback (nor can the driver fail the operation by returning an error). If stats can't be reported the relevant attributes will be empty. Signed-off-by: Jakub Kicinski <kuba@kernel.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2021-04-11ethtool: Allow network drivers to dump arbitrary EEPROM dataVladyslav Tarasiuk
Define get_module_eeprom_by_page() ethtool callback and implement netlink infrastructure. get_module_eeprom_by_page() allows network drivers to dump a part of module's EEPROM specified by page and bank numbers along with offset and length. It is effectively a netlink replacement for get_module_info() and get_module_eeprom() pair, which is needed due to emergence of complex non-linear EEPROM layouts.

2021-03-31ethtool: support FEC settings over netlinkJakub Kicinski
Add FEC API to netlink. This is not a 1-to-1 conversion. FEC settings already depend on link modes to tell user which modes are supported. Take this further an use link modes for manual configuration. Old struct ethtool_fecparam is still used to talk to the drivers, so we need to translate back and forth. We can revisit the internal API if number of FEC encodings starts to grow. Enforce only one active FEC bit (by using a bit position rather than another mask).

2021-02-03ethtool: Extend link modes settings uAPI with lanesDanielle Ratson
Currently, when auto negotiation is on, the user can advertise all the linkmodes which correspond to a specific speed, but does not have a similar selector for the number of lanes. This is significant when a specific speed can be achieved using different number of lanes. For example, 2x50 or 4x25. Add 'ETHTOOL_A_LINKMODES_LANES' attribute and expand 'struct ethtool_link_settings' with lanes field in order to implement a new lanes-selector that will enable the user to advertise a specific number of lanes as well. When auto negotiation is off, lanes parameter can be forced only if the driver supports it. Add a capability bit in 'struct ethtool_ops' that allows ethtool know if the driver can handle the lanes parameter when auto negotiation is off, so if it does not, an error message will be returned when trying to set lanes. Example: $ ethtool -s swp1 lanes 4 $ ethtool swp1 Settings for swp1: Supported ports: [ FIBRE ] Supported link modes: 1000baseKX/Full 10000baseKR/Full 40000baseCR4/Full 40000baseSR4/Full 40000baseLR4/Full 25000baseCR/Full 25000baseSR/Full 50000baseCR2/Full 100000baseSR4/Full 100000baseCR4/Full Supported pause frame use: Symmetric Receive-only Supports auto-negotiation: Yes Supported FEC modes: Not reported Advertised link modes: 40000baseCR4/Full 40000baseSR4/Full 40000baseLR4/Full 100000baseSR4/Full 100000baseCR4/Full Advertised pause frame use: No Advertised auto-negotiation: Yes Advertised FEC modes: Not reported Speed: Unknown!

2020-09-17ethtool: add and use message type for tunnel info replyMichal Kubecek
Tunnel offload info code uses ETHTOOL_MSG_TUNNEL_INFO_GET message type (cmd field in genetlink header) for replies to tunnel info netlink request, i.e. the same value as the request have. This is a problem because we are using two separate enums for userspace to kernel and kernel to userspace message types so that this ETHTOOL_MSG_TUNNEL_INFO_GET (28) collides with ETHTOOL_MSG_CABLE_TEST_TDR_NTF which is what message type 28 means for kernel to userspace messages. As the tunnel info request reached mainline in 5.9 merge window, we should still be able to fix the reply message type without breaking backward compatibility.

2020-09-15ethtool: add standard pause statsJakub Kicinski
Currently drivers have to report their pause frames statistics via ethtool -S, and there is a wide variety of names used for these statistics. Add the two statistics defined in IEEE 802.3x to the standard API. Create a new ethtool request header flag for including statistics in the response to GET commands. Always create the ETHTOOL_A_PAUSE_STATS nest in replies when flag is set. Testing if driver declares the op is not a reliable way of checking if any stats will actually be included and therefore we don't want to give the impression that presence of ETHTOOL_A_PAUSE_STATS indicates driver support. Note that this patch does not include PFC counters, which may fit better in dcbnl? But mostly I don't need them/have a setup to test them so I haven't looked deeply into exposing them :) v3: - add a helper for "uninitializing" stats, rather than a cryptic memset() (Andrew) Signed-off-by: Jakub Kicinski <kuba@kernel.org> Reviewed-by: Saeed Mahameed <saeedm@nvidia.com> Signed-off-by: David S.

2020-08-03udp_tunnel: add the ability to hard-code IANA VXLANJakub Kicinski
mlx5 has the IANA VXLAN port (4789) hard coded by the device, instead of being added dynamically when tunnels are created. To support this add a workaround flag to struct udp_tunnel_nic_info. Skipping updates for the port is fairly trivial, dumping the hard coded port via ethtool requires some code duplication. The port is not a part of any real table, we dump it in a special table which has no tunnel types supported and only one entry. This is the last known workaround / hack needed to convert all drivers to the new infra. Signed-off-by: Jakub Kicinski <kuba@kernel.org> Signed-off-by: Saeed Mahameed <saeedm@mellanox.com>
2020-07-10ethtool: add tunnel info interfaceJakub Kicinski
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.

2020-05-06ethtool: provide UAPI for PHY master/slave configuration.Oleksij Rempel
This UAPI is needed for BroadR-Reach 100BASE-T1 devices. Due to lack of auto-negotiation support, we needed to be able to configure the MASTER-SLAVE role of the port manually or from an application in user space. The same UAPI can be used for 1000BASE-T or MultiGBASE-T devices to force MASTER or SLAVE role. See IEEE 802.3-2018: 22.2.4.3.7 MASTER-SLAVE control register (Register 9) 22.2.4.3.8 MASTER-SLAVE status register (Register 10) 40.5.2 MASTER-SLAVE configuration resolution 45.2.1.185.1 MASTER-SLAVE config value (1.2100.14) 45.2.7.10 MultiGBASE-T AN control 1 register (Register 7.32) The MASTER-SLAVE role affects the clock configuration: ------------------------------------------------------------------------------- When the PHY is configured as MASTER, the PMA Transmit function shall source TX_TCLK from a local clock source.

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>

2020-01-27ethtool: add WOL_NTF notificationMichal Kubecek
Send ETHTOOL_MSG_WOL_NTF notification whenever wake-on-lan settings of a device are modified using ETHTOOL_MSG_WOL_SET netlink message or ETHTOOL_SWOL ioctl request. As notifications can be received by anyone, do not include SecureOn(tm) password in notification messages. Signed-off-by: Michal Kubecek <mkubecek@suse.cz> Signed-off-by: David S.

2020-01-27ethtool: add DEBUG_NTF notificationMichal Kubecek
Send ETHTOOL_MSG_DEBUG_NTF notification message whenever debugging message mask for a device are modified using ETHTOOL_MSG_DEBUG_SET netlink message or ETHTOOL_SMSGLVL ioctl request. The notification message has the same format as reply to DEBUG_GET request. As with other ethtool notifications, netlink requests only trigger the notification if the mask is actually changed while ioctl request trigger it whenever the request results in calling the ethtool_ops handler.

2020-01-27ethtool: set message mask with DEBUG_SET requestMichal Kubecek
Implement DEBUG_SET netlink request to set debugging settings for a device. At the moment, only message mask corresponding to message level as set by ETHTOOL_SMSGLVL ioctl request can be set. (It is called message level in ioctl interface but almost all drivers interpret it as a bit mask.)
