Commit ca893194 ("net: dsa: b53: Keep CPU port as tagged in all VLANs") forced the CPU port to be always tagged in any VLAN membership. This was necessary back then because we did not support Broadcom tags for all configurations so the only way to differentiate tagged and untagged traffic while DSA_TAG_PROTO_NONE was used was to force the CPU port into being always tagged. With most configurations enabling Broadcom tags, especially after 8fab459e ("net: dsa: b53: Enable Broadcom tags for 531x5/539x families") we do not need to apply this unconditional force tagging of the CPU port in all VLANs. A helper function is introduced to faciliate the encapsulation of the specific condition requiring the CPU port to be tagged in all VLANs and the dsa_switch_ops::untag_bridge_pvid boolean is moved to when dsa_switch_ops::setup is called when we have already determined the tagging protocol we will be using.

We are currently assuming that GMAC_AHB_RESET will already be deasserted by the bootloader. However if this has not been done, probing of the GMAC will fail. To remedy this we must ensure GMAC_AHB_RESET has been deasserted prior to probing. v2 changes: - remove NULL condition check for stmmac_ahb_rst in stmmac_main.c - unwrap dev_err() message in stmmac_main.c - add PTR_ERR() around plat->stmmac_ahb_rst in stmmac_platform.c v3 changes: - add error pointer to dev_err() output - add reset_control_assert(stmmac_ahb_rst) in stmmac_dvr_remove - revert PTR_ERR() around plat->stmmac_ahb_rst since this is performed on the returned value of ret by the calling function Signed-off-by:

priv->plat->mdio_bus_data is optional, some platforms may not set it, however we proceed to look straight at priv->plat->mdio_bus_data->has_xpcs. Since the xpcs is instantiated based on the has_xpcs property, we can avoid looking at the priv->plat->mdio_bus_data structure altogether and just check for the presence of the xpcs pointer.

IMP(Intelligent Management Processor) firmware add a new feature to handle and consolidate RAS information for new devices, NIC driver only needs to query the reported RAS information. NIC driver adds support for this feature. Driver queries device capability to check whether IMP support this feature, If yes, execute the new RAS processing branch. In order to add a method to check whether PF supports imp-handle RAS feature, add dumping this info in debugfs. Signed-off-by:

To adapt to hardware modification and ensure that the driver is compatible with the original error handling content, we need to add the RAS compatibility adaptation solution. Add a processing branch to the driver during error handling. In the new processing branch, NIC fault information is integrated by the IMP. An interaction command is added between the driver and IMP to query and clear the fault source and interrupt source. The IMP integrates error information and reports the highest reset level to the driver. Signed-off-by:

Currently, hardware errors can be reported through AER or MSI-X mode. However, the AER mode is intended to handle only bus errors, but not hardware errors. On the other hand, virtual machines cannot handle AER errors. When an AER error is reported, virtual machines will be suspended. So add support for handling all these hardware errors through MSI-X mode which depends on a newer version of firmware, and reserve the handler of the AER mode for compatibility. Signed-off-by:

This tweaks several small places to improve the data access in fast path: * Remove duplicates of first_interrupt flag and surround it with WRITE/READ_ONCE macros: The flag is used to detect HW disorders in its interrupt communication with the driver. The flag is set when an interrupt is received and used in the health check function (ena_timer_service()) to help it find irregularities. * Reorder some fields in ena_napi struct to take better advantage of cache access pattern. * Move XDP TX queue number to a variable to save its calculation for every packet. * Use likely in a condition to improve branch prediction The 'first_interrupt' and 'interrupt_masked' flags were moved to reside in the same cache line as the first fields of 'napi' struct. This placement ensures that all memory accessed during upper-half handler reside in the same cacheline (napi_schedule_irqoff() only accesses 'state' and 'poll_list' fields which are at the beginning of napi struct).

Ido Schimmel says: ==================== mlxsw: Various updates This patchset contains various updates for mlxsw. The most significant change is the long overdue removal of the abort mechanism in the first two patches. Patches #1-#2 remove the route abort mechanism. This change is long overdue and explained in detail in the commit message. Patch #3 sets ports down in a few selftests that forgot to do so. Discovered using a BPF tool (WIP) that monitors ASIC resources. Patch #4 fixes an issue introduced by commit 557c4d2f ("selftests: devlink_lib: add check for devlink device existence"). Patches #5-#8 modify the driver to read transceiver module's temperature thresholds using MTMP register (when supported) instead of directly from the module's EEPROM using MCIA register. This is both more reliable and more efficient as now the module's temperature and thresholds are read using one transaction instead of three. ==================== Signed-off-by:

mlxsw_thermal_module_trips_update() is used to update the trip points of the module's thermal zone. Currently, this is done by querying the thresholds from the module's EEPROM via MCIA register. This data does not pass validation and in some cases can be unreliable. For example, due to some problem with transceiver module. Previous patch made it possible to read module's temperature and thresholds via MTMP register. Therefore, extend mlxsw_thermal_module_trips_update() to use the thresholds queried from MTMP, if valid. This is both more reliable and more efficient than current method, as temperature and thresholds are queried in one transaction instead of three. This is significant when working over a slow bus such as I2C. Signed-off-by:

Provide new function mlxsw_thermal_module_temp_and_thresholds_get() for reading temperature and temperature thresholds by a single operation. The motivation is to reduce the number of transactions with the device which is important when operating over a slow bus such as I2C. Currently, the sole caller of the function is only using it to read the module's temperature. The next patch will also use it to query the module's temperature thresholds. Signed-off-by:

Currently, module temperature thresholds are obtained from Management Cable Info Access (MCIA) register by specifying the thresholds offsets within module EEPROM layout. This data does not pass validation and in some cases can be unreliable. For example, due to some problem with the module. Add support for a new feature provided by Management Temperature (MTMP) register for sanitization of temperature thresholds values. Extend mlxsw_env_module_temp_thresholds_get() to get temperature thresholds through MTMP field 'max_operational_temperature' - if it is not zero, feature is supported. Otherwise fallback to old method and get the thresholds through MCIA. Signed-off-by:

Extend Management Temperature (MTMP) register with new field specifying the maximum temperature threshold. Extend mlxsw_reg_mtmp_unpack() function with two extra arguments, providing high and maximum temperature thresholds. For modules, these thresholds correspond to critical and emergency thresholds that are read from the module's EEPROM. Signed-off-by:

In the commit referenced below, a check was added to devlink_lib that asserts the existence of a devlink device referenced by $DEVLINK_DEV. Unfortunately, several netdevsim tests point DEVLINK_DEV at a device that does not exist at the time that devlink_lib is sourced. Thus these tests spuriously fail. Fix this by introducing an override. By setting DEVLINK_DEV to an empty string, the user declares their intention to handle DEVLINK_DEV management on their own. In all netdevsim tests that use devlink_lib and set DEVLINK_DEV, set instead an empty DEVLINK_DEV just before sourcing devlink_lib, and set it to the correct value right afterwards.

To check how many routes are installed in hardware, the test runs "ip route" and greps for "offload", which includes routes with state "offload_failed". Till now, this wrong check was not found because after one failure in route insertion, the driver moved to "abort" mode, which means that user cannot try to add more routes. The previous patch removed the abort mechanism and now failed routes are counted as offloaded. Fix this by not considering routes with "offload_failed" flag as offloaded. Signed-off-by:
