Add label attribute to hwmon object for exposing QSFP module's temperature sensor name. Modules are labeled as "front panel xxx". The label is used by utilities such as "sensors": front panel 001: +0.0C (crit = +0.0C, emerg = +0.0C) .. front panel 020: +31.0C (crit = +70.0C, emerg = +80.0C) .. front panel 056: +41.0C (crit = +70.0C, emerg = +80.0C) Signed-off-by:

Add new attributes to hwmon object for exposing QSFP module temperature input, fault indication, critical and emergency thresholds. Temperature input and fault indication are read from Management Temperature Bulk Register. Temperature thresholds are read from Management Cable Info Access Register. Signed-off-by:

Rename cooling device from "Fan" to "mlxsw_fan". Name "Fan" is too common name, and such name is misleading, while it's interpreted by user. For example name "Fan" could be used by ACPI. Signed-off-by:

Modify thermal zone trip points setting for better alignment with system thermal requirement. Add hysteresis thresholds for thermal trips in order to avoid throttling around thermal trip point. If hysteresis temperature is not considered, PWM can have side effect of flip up/down on thermal trip point boundary. Signed-off-by:

Add low frequency bus capability in order to allow core functionality separation based on bus type. Driver could run over PCIe, which is considered as high frequency bus or I2C, which is considered as low frequency bus. In the last case time setting, for example, for thermal polling interval, should be increased. Use different thermal monitoring based on bus type. For I2C bus time is set to 20 seconds, while for PCIe 1 second polling interval is used. Signed-off-by:

We need to set the error message on this path otherwise some of the callers, such as test_hints_case(), print from an uninitialized pointer. We had a similar bug earlier and set "errmsg" to NULL in the caller, test_delta_action_item(). That code is no longer required so I have removed it.

Jesper Dangaard Brouer says: ==================== Fix page_pool API and dma address storage As pointed out by David Miller in [1] the current page_pool implementation stores dma_addr_t in page->private. This won't work on 32-bit platforms with 64-bit DMA addresses since the page->private is an unsigned long and the dma_addr_t a u64. Since no driver is yet using the DMA mapping capabilities of the API let's fix this by storing the information in 'struct page' and use that to store and retrieve DMA addresses from network drivers. As long as the addresses returned from dma_map_page() are aligned the first bit, used by the compound pages code should not be set. Ilias tested the first two patches on Espressobin driver mvneta, for which we have patches for using the DMA API of page_pool.

As pointed out by Alexander Duyck, the DMA mapping done in page_pool needs to use the DMA attribute DMA_ATTR_SKIP_CPU_SYNC. As the principle behind page_pool keeping the pages mapped is that the driver takes over the DMA-sync steps. Reported-by:

This won't work on 32-bit platforms with 64-bit DMA addresses since the page->private is an unsigned long and the dma_addr_t a u64. A previous patch is adding dma_addr_t on struct page to accommodate this. This patch adapts the page_pool related functions to use the newly added struct for storing and retrieving DMA addresses from network drivers. Signed-off-by:

With the introduction of flow_stats_update(), drivers now update the stats fields of the passed tc_cls_flower_offload struct, rather than call tcf_exts_stats_update() directly to update the stats of offloaded TC flower rules. However, if multiple qdiscs are registered to a TC shared block and a flower rule is applied, then, when getting stats for the rule, multiple callbacks may be made. Take this into consideration by modifying flow_stats_update to gather the stats from all callbacks. Currently, the values in tc_cls_flower_offload only account for the last stats callback in the list.

Recently introduced tc_setup_flow_action() can fail when parsing tcf_exts on some unsupported action commands. However, this should not affect the case when user did not explicitly request hw offload by setting skip_sw flag. Modify tc_setup_flow_action() callers to only propagate the error if skip_sw flag is set for filter that is being offloaded, and set extack error message in that case. Signed-off-by:

Maxime Chevallier says: ==================== net: phy: Add 2.5G/5GBASET PHYs support The 802.3bz standard defines 2 modes based on the NBASET alliance work that allow to use 2.5Gbps and 5Gbps speeds on Cat 5e, 6 and 7 cables. This series adds the necessary infrastructure to handle these modes with C45 PHYs. This series was originally part of a bigger one, that has seen 2 iterations [1] [2] that added support for these modes on Marvell Alaska PHYs. Following some discussions with Heiner and Andrew [3], we decided to split-out the generic parts so that we can work together on the following steps to get these mode fully working with Aquantia and Marvell PHYS. The first 3 patches are reworking some of the internal network phy infrastructure to handle the new modes in a more generic way. The 4th patch adds all the C45 register definition and accesses that follows the 802.3bz standard to support 2.5GBASET and 5GBASET.

The 802.3bz specification, based on previous by the NBASET alliance, defines the 2.5GBaseT and 5GBaseT link modes for ethernet traffic on cat5e, cat6 and cat7 cables. These mode integrate with the already defined C45 MDIO PMA/PMD registers set that added 10G support, by defining some previously reserved bits, and adding a new register (2.5G/5G Extended abilities). This commit adds the required definitions in include/uapi/linux/mdio.h to support these modes, and detect when a link-partner advertises them. It also adds support for these mode in the generic C45 PHY infrastructure. Signed-off-by:

Marvell 10G PHY driver has a generic way of initializing the supported link modes by reading the PHY's C45 PMA abilities. This can be made generic, since these registers are part of the 802.3 specifications. This commit extracts the config_init link_mode initialization code from marvell10g and uses it to introduce the genphy_c45_pma_read_abilities function. Only PMA modes are read, it's still up to the caller to set the Pause parameters. Signed-off-by:
