A lot of places pass netdev->dev_addr to of_get_ethdev_address() and device_get_ethdev_addr() so this set adds new functions which wrap the functionality. v2 performs suggested code moves, adds a couple additional clean ups on the device property side, and an extra patch converting drivers which can benefit from device_get_ethdev_address(). v3 removes OF_NET and corrects kdoc. ==================== Signed-off-by: -

Commit 406f42fa ("net-next: When a bond have a massive amount of VLANs...") introduced a rbtree for faster Ethernet address look up. To maintain netdev->dev_addr in this tree we need to make all the writes to it got through appropriate helpers. There is a handful of drivers which pass netdev->dev_addr as the destination buffer to device_get_mac_address(). Add a helper which takes a dev pointer instead, so it can call an appropriate helper.

fwnode_get_mac_address() and device_get_mac_address() return a pointer to the buffer that was passed to them on success or NULL on failure. None of the callers care about the actual value, only if it's NULL or not. These semantics differ from of_get_mac_address() which returns an int so to avoid confusion make the device helpers return an errno. Signed-off-by:

Ido Schimmel says: ==================== ethtool: Add ability to control transceiver modules' power mode This patchset extends the ethtool netlink API to allow user space to control transceiver modules. Two specific APIs are added, but the plan is to extend the interface with more APIs in the future (see "Future plans"). This submission is a complete rework of a previous submission [1] that tried to achieve the same goal by allowing user space to write to the EEPROMs of these modules. It was rejected as it could have enabled user space binary blob drivers. However, the main issue is that by directly writing to some pages of these EEPROMs, we are interfering with the entity that is controlling the modules (kernel / device firmware). In addition, some functionality cannot be implemented solely by writing to the EEPROM, as it requires the assertion / de-assertion of hardware signals (e.g., "ResetL" pin in SFF-8636). Motivation ========== The kernel can currently dump the contents of module EEPROMs to user space via the ethtool legacy ioctl API or the new netlink API. These dumps can then be parsed by ethtool(8) according to the specification that defines the memory map of the EEPROM. For example, SFF-8636 [2] for QSFP and CMIS [3] for QSFP-DD. In addition to read-only elements, these specifications also define writeable elements that can be used to control the behavior of the module. For example, controlling whether the module is put in low or high power mode to limit its power consumption. The CMIS specification even defines a message exchange mechanism (CDB, Command Data Block) on top of the module's memory map. This allows the host to send various commands to the module. For example, to update its firmware. Implementation ============== The ethtool netlink API is extended with two new messages, 'ETHTOOL_MSG_MODULE_SET' and 'ETHTOOL_MSG_MODULE_GET', that allow user space to set and get transceiver module parameters. Specifically, the 'ETHTOOL_A_MODULE_POWER_MODE_POLICY' attribute allows user space to control the power mode policy of the module in order to limit its power consumption. See detailed description in patch #1. The user API is designed to be generic enough so that it could be used for modules with different memory maps (e.g., SFF-8636, CMIS). The only implementation of the device driver API in this series is for a MAC driver (mlxsw) where the module is controlled by the device's firmware, but it is designed to be generic enough so that it could also be used by implementations where the module is controlled by the kernel. Testing and introspection ========================= See detailed description in patches #1 and #5. Patchset overview ================= Patch #1 adds the initial infrastructure in ethtool along with the ability to control transceiver modules' power mode. Patches #2-#3 add required device registers in mlxsw. Patch #4 implements in mlxsw the ethtool operations added in patch #1. Patch #5 adds extended link states in order to allow user space to troubleshoot link down issues related to transceiver modules. Patch #6 adds support for these extended states in mlxsw. Future plans ============ * Extend 'ETHTOOL_MSG_MODULE_SET' to control Tx output among other attributes. * Add new ethtool message(s) to update firmware on transceiver modules. * Extend ethtool(8) to parse more diagnostic information from CMIS modules. No kernel changes required.

Add an extended state and sub-state to describe link issues related to transceiver modules. The 'ETHTOOL_LINK_EXT_SUBSTATE_MODULE_CMIS_NOT_READY' extended sub-state tells user space that port is unable to gain a carrier because the CMIS Module State Machine did not reach the ModuleReady (Fully Operational) state. For example, if the module is stuck at ModuleLowPwr or ModuleFault state. In case of the latter, user space can read the fault reason from the module's EEPROM and potentially reset it. Signed-off-by:

Implement support for ethtool_ops::.get_module_power_mode and ethtool_ops::set_module_power_mode. The get operation is implemented using the Management Cable IO and Notifications (MCION) register that reports the operational power mode of the module and its presence. In case a module is not present, its operational power mode is not reported to ethtool and user space. If not set before, the power mode policy is reported as "high", which is the default on Mellanox systems. The set operation is implemented using the Port Module Memory Map Properties (PMMP) register. The register instructs the device's firmware to transition a plugged-in module to / out of low power mode by writing to its memory map. When the power mode policy is set to 'auto', a module will not transition to low power mode as long as any ports using it are administratively up. Example: # devlink port split swp11 count 4 # ethtool --set-module swp11s0 power-mode-policy auto $ ethtool --show-module swp11s0 Module parameters for swp11s0: power-mode-policy auto power-mode low # ip link set dev swp11s0 up # ip link set dev swp11s1 up $ ethtool --show-module swp11s0 Module parameters for swp11s0: power-mode-policy auto power-mode high # ip link set dev swp11s1 down $ ethtool --show-module swp11s0 Module parameters for swp11s0: power-mode-policy auto power-mode high # ip link set dev swp11s0 down $ ethtool --show-module swp11s0 Module parameters for swp11s0: power-mode-policy auto power-mode low Signed-off-by:

Ido Schimmel authored
Add a pair of new ethtool messages, 'ETHTOOL_MSG_MODULE_SET' and 'ETHTOOL_MSG_MODULE_GET', that can be used to control transceiver modules parameters and retrieve their status. The first parameter to control is the power mode of the module. It is only relevant for paged memory modules, as flat memory modules always operate in low power mode. When a paged memory module is in low power mode, its power consumption is reduced to the minimum, the management interface towards the host is available and the data path is deactivated. User space can choose to put modules that are not currently in use in low power mode and transition them to high power mode before putting the associated ports administratively up. This is useful for user space that favors reduced power consumption and lower temperatures over reduced link up times. In QSFP-DD modules the transition from low power mode to high power mode can take a few seconds and this transition is only expected to get longer with future / more complex modules. User space can control the power mode of the module via the power mode policy attribute ('ETHTOOL_A_MODULE_POWER_MODE_POLICY'). Possible values: * high: Module is always in high power mode. * auto: Module is transitioned by the host to high power mode when the first port using it is put administratively up and to low power mode when the last port using it is put administratively down. The operational power mode of the module is available to user space via the 'ETHTOOL_A_MODULE_POWER_MODE' attribute. The attribute is not reported to user space when a module is not plugged-in. The user API is designed to be generic enough so that it could be used for modules with different memory maps (e.g., SFF-8636, CMIS). The only implementation of the device driver API in this series is for a MAC driver (mlxsw) where the module is controlled by the device's firmware, but it is designed to be generic enough so that it could also be used by implementations where the module is controlled by the CPU.
