2024-08-22net: airoha: configure hw mac address according to the port idLorenzo Bianconi
GDM1 port on EN7581 SoC is connected to the lan dsa switch. GDM{2,3,4} can be used as wan port connected to an external phy module. Configure hw mac address registers according to the port id.

2024-08-21net: xilinx: axienet: Add statistics supportSean Anderson
Add support for reading the statistics counters, if they are enabled. The counters may be 64-bit, but we can't detect this statically as there's no ability bit for it and the counters are read-only. Therefore, we assume the counters are 32-bits by default. To ensure we don't miss an overflow, we read all counters at 13-second intervals. This should be often enough to ensure the bytes counters don't wrap at 2.5 Gbit/s. Another complication is that the counters may be reset when the device is reset (depending on configuration). To ensure the counters persist across link up/down (including suspend/resume), we maintain our own versions along with the last counter value we saw. Because we might wait up to 100 ms for the reset to complete, we use a mutex to protect writing hw_stats. We can't sleep in ndo_get_stats64, so we use a seqlock to protect readers. We don't bother disabling the refresh work when we detect 64-bit counters. This is because the reset issue requires us to read hw_stat_base and reset_in_progress anyway, which would still require the seqcount. And I don't think skipping the task is worth the extra bookkeeping. We can't use the byte counters for either get_stats64 or get_eth_mac_stats. This is because the byte counters include everything in the frame (destination address to FCS, inclusive). But rtnl_link_stats64 wants bytes excluding the FCS, and ethtool_eth_mac_stats wants to exclude the L2 overhead (addresses and length/type). It might be possible to calculate the byte values Linux expects based on the frame counters, but I think it is simpler to use the existing software counters. get_ethtool_stats is implemented for nonstandard statistics. This includes the aforementioned byte counters, VLAN and PFC frame counters, and user-defined (e.g. with custom RTL) counters.

2024-08-21net: xilinx: axienet: Report RxRject as rx_droppedSean Anderson
The Receive Frame Rejected interrupt is asserted whenever there was a receive error (bad FCS, bad length, etc.) or whenever the frame was dropped due to a mismatched address. So this is really a combination of rx_otherhost_dropped, rx_length_errors, rx_frame_errors, and rx_crc_errors. Mismatched addresses are common and aren't really errors at all (much like how fragments are normal on half-duplex links). To avoid confusion, report these events as rx_dropped. This better reflects what's going on: the packet was received by the MAC but dropped before being processed.

2024-08-21net: wwan: t7xx: PCIe reset rescanJinjian Song
WWAN device is programmed to boot in normal mode or fastboot mode, when triggering a device reset through ACPI call or fastboot switch command. Maintain state machine synchronization and reprobe logic after a device reset. The PCIe device reset triggered by several ways. E.g.: - fastboot: echo "fastboot_switching" > /sys/bus/pci/devices/${bdf}/t7xx_mode. - reset: echo "reset" > /sys/bus/pci/devices/${bdf}/t7xx_mode. - IRQ: PCIe device request driver to reset itself by an interrupt request. Use pci_reset_function() as a generic way to reset device, save and restore the PCIe configuration before and after reset device to ensure the reprobe process.

2024-08-16bnx2x: Set ivi->vlan field as an integerSimon Horman
In bnx2x_get_vf_config(): * The vlan field of ivi is a 32-bit integer, it is used to store a vlan ID. * The vlan field of bulletin is a 16-bit integer, it is also used to store a vlan ID. In the current code, ivi->vlan is set using memset. But in the case of setting it to the value of bulletin->vlan, this involves reading 32 bits from a 16bit source. This is likely safe, as the following 6 bytes are padding in the same structure, but none the less, it seems undesirable. However, it is entirely unclear to me how this scheme works on big-endian systems. Resolve this by simply assigning integer values to ivi->vlan.

git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/next-queue Tony Nguyen says: ==================== ice: iavf: add support for TC U32 filters on VFs Ahmed Zaki says: The Intel Ethernet 800 Series is designed with a pipeline that has an on-chip programmable capability called Dynamic Device Personalization (DDP). A DDP package is loaded by the driver during probe time. The DDP package programs functionality in both the parser and switching blocks in the pipeline, allowing dynamic support for new and existing protocols. Once the pipeline is configured, the driver can identify the protocol and apply any HW action in different stages, for example, direct packets to desired hardware queues (flow director), queue groups or drop. Patches 1-8 introduce a DDP package parser API that enables different pipeline stages in the driver to learn the HW parser capabilities from the DDP package that is downloaded to HW. The parser library takes raw packet patterns and masks (in binary) indicating the packet protocol fields to be matched and generates the final HW profiles that can be applied at the required stage. With this API, raw flow filtering for FDIR or RSS could be done on new protocols or headers without any driver or Kernel updates (only need to update the DDP package). These patches were submitted before [1] but were not accepted mainly due to lack of a user. Patches 9-11 extend the virtchnl support to allow the VF to request raw flow director filters. Upon receiving the raw FDIR filter request, the PF driver allocates and runs a parser lib instance and generates the hardware profile definitions required to program the FDIR stage. These were also submitted before [2]. Finally, patches 12 and 13 add TC U32 filter support to the iavf driver. Using the parser API, the ice driver runs the raw patterns sent by the user and then adds a new profile to the FDIR stage associated with the VF's VSI. Refer to examples in patch 13 commit message.

2024-08-15virtio: allow driver to disable the configure change notificationJason Wang
Sometime, it would be useful to disable the configure change notification from the driver. So this patch allows this by introducing a variable config_change_driver_disabled and only allow the configure change notification callback to be triggered when it is allowed by both the virtio core and the driver. It is set to false by default to hold the current semantic so we don't need to change any drivers. The first user for this would be virtio-net.

2024-08-15net/mlx5: Use cpumask_local_spread() instead of custom codeErwan Velu
Commit 2acda57736de ("net/mlx5e: Improve remote NUMA preferences used for the IRQ affinity hints") removed the usage of cpumask_local_spread(). The issue explained in this commit was fixed by commit 406d394abfcd ("cpumask: improve on cpumask_local_spread() locality"). Since this commit, mlx5_cpumask_default_spread() is having the same behavior as cpumask_local_spread(). This commit is about : - removing the specific logic and use cpumask_local_spread() instead - passing mlx5_core_dev as argument to more flexibility mlx5_cpumask_default_spread() is kept as it could be useful for some future specific quirks.

The recent change fixed the one place that didn't respect the D_SENSE bit. However, it turns out that hdparm, hddtemp and udisks (incorrectly) assumes sense data in descriptor format. Therefore, even while the change was technically correct, revert it, since even if these user space programs are fixed to (correctly) look at the format type before parsing the data, older versions of these tools will be around roughly forever. * tag 'ata-6.11-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/libata/linux: Revert "ata: libata-scsi: Honor the D_SENSE bit for CK_COND=1 and no error"

2024-08-15pse-core: Conditionally set current limit during PI regulator registrationOleksij Rempel
Fix an issue where `devm_regulator_register()` would fail for PSE controllers that do not support current limit control, such as simple GPIO-based controllers like the podl-pse-regulator. The `REGULATOR_CHANGE_CURRENT` flag and `max_uA` constraint are now conditionally set only if the `pi_set_current_limit` operation is supported. This change prevents the regulator registration routine from attempting to call `pse_pi_set_current_limit()`, which would return `-EOPNOTSUPP` and cause the registration to fail.

2024-08-15net: thunder_bgx: Fix netdev structure allocationMarc Zyngier
Commit 94833addfaba ("net: thunderx: Unembed netdev structure") had a go at dynamically allocating the netdev structures for the thunderx_bgx driver. This change results in my ThunderX box catching fire (to be fair, it is what it does best). The issues with this change are that: - bgx_lmac_enable() is called *after* bgx_acpi_register_phy() and bgx_init_of_phy(), both expecting netdev to be a valid pointer. - bgx_init_of_phy() populates the MAC addresses for *all* LMACs attached to a given BGX instance, and thus needs netdev for each of them to have been allocated. There is a few things to be said about how the driver mixes LMAC and BGX states which leads to this sorry state, but that's beside the point. To address this, go back to a situation where all netdev structures are allocated before the driver starts relying on them, and move the freeing of these structures to driver removal. Someone brave enough can always go and restructure the driver if they want.
