2025-06-17net: phy: Add c45_phy_ids sysfs directory entryYajun Deng
The phy_id field only shows the PHY ID of the C22 device, and the C45 device did not store its PHY ID in this field. Add a new phy_mmd_group, and export the mmd<n>_device_id for the C45 device. These files are invisible to the C22 device.

2025-06-17net: enetc: replace PCVLANR1/2 with SICVLANR1/2 and remove dead branchWei Fang
Both PF and VF have rx-vlan-offload enabled, however, the PCVLANR1/2 registers are resources controlled by PF, so VF cannot access these two registers. Fortunately, the hardware provides SICVLANR1/2 registers for each SI to reflect the value of PCVLANR1/2 registers. Therefore, use SICVLANR1/2 instead of PCVLANR1/2. Note that this is not an issue in actual use, because the current driver does not support custom TPID, the driver will not access these two registers in actual use, so this modification is just an optimization. In addition, since ENETC_RXBD_FLAG_TPID is defined as GENMASK(1, 0), the possible values are only 0, 1, 2, 3, so the default branch will never be true, so remove the default branch.

2025-06-17net: mana: Allocate MSI-X vectors dynamicallyShradha Gupta
Currently, the MANA driver allocates MSI-X vectors statically based on MANA_MAX_NUM_QUEUES and num_online_cpus() values and in some cases ends up allocating more vectors than it needs. This is because, by this time we do not have a HW channel and do not know how many IRQs should be allocated. To avoid this, we allocate 1 MSI-X vector during the creation of HWC and after getting the value supported by hardware, dynamically add the remaining MSI-X vectors.

2025-06-17net: mana: Allow irq_setup() to skip cpus for affinityShradha Gupta
In order to prepare the MANA driver to allocate the MSI-X IRQs dynamically, we need to enhance irq_setup() to allow skipping affinitizing IRQs to the first CPU sibling group. This would be for cases when the number of IRQs is less than or equal to the number of online CPUs. In such cases for dynamically added IRQs the first CPU sibling group would already be affinitized with HWC IRQ.

2025-06-16eth: gianfar: migrate to new RXFH callbacksJakub Kicinski
Migrate to new callbacks added by commit 9bb00786fc61 ("net: ethtool: add dedicated callbacks for getting and setting rxfh fields"). Uniquely, this driver supports only the SET operation. It does not support GET at all. The SET callback also always returns 0, even tho it checks a bunch of conditions, and if my quick reading is right, expects the user to insert filtering rules for given flow type first? Long story short it seems too convoluted to easily add the GET as part of the conversion.

Along with other changes the mailbox communication mechanism between RVU (Resource virtualization Unit) SRIOV PFs/VFs with Admin function (AF) has also gone through some changes. Some of those changes are - Separate IRQs for mbox request and response/ack. - Configurable mbox size, default being 64KB. - Ability for VFs to communicate with RVU AF instead of going through parent SRIOV PF. Due to more memory requirement due to configurable mbox size, mbox memory will now have to be allocated by - AF (PF0) for communicating with other PFs and all VFs in the system. - PF for communicating with it's child VFs. On previous silicons mbox memory was reserved and configured by firmware. This patch series add basic mbox support for AF (PF0) <=> PFs and PF <=> VFs. AF <=> VFs communication and variable mbox size support will come in later. Patch #1 Supported co-existance of bit encoding PFs and VFs in 16-bit hardware pcifunc format between CN20K silicon and older octeon series. Also exported PF,VF masks and shifts present in mailbox module to all other modules. Patch #2 Added basic mbox operation APIs and structures to support both CN20K and previous version of silicons.

Number of RVU PFs on CN20K silicon have increased to 96 from maximum of 32 that were supported on earlier silicons. Every RVU PF and VF is identified by HW using a 16bit PF_FUNC value. Due to the change in Max number of PFs in CN20K, the bit encoding of this PF_FUNC has changed. This patch handles the change by using helper functions(using silicon check) to use PF,VF masks and shifts to support both new silicon CN20K, OcteonTx series. These helper functions are used in different modules. Also moved the NIX AF register offset macros to other files which will be posted in coming patches.

seg6_lookup_nexthop() is a wrapper around seg6_lookup_any_nexthop().

2025-06-16seg6: Extend seg6_lookup_any_nexthop() with an oif argumentIdo Schimmel
seg6_lookup_any_nexthop() is called by the different endpoint behaviors (e.g., End, End.X) to resolve an IPv6 route. Extend the function with an output interface argument so that it could be used to resolve a route with a certain output interface. This will be used by subsequent patches that will extend the End.X behavior with an output interface as an optional argument. ip6_route_input_lookup() cannot be used when an output interface is specified as it ignores this parameter. Similarly, calling ip6_pol_route() when a table ID was not specified (e.g., End.X behavior) is wrong. Therefore, when an output interface is specified without a table ID, resolve the route using ip6_route_output() which will take the output interface into account. Note that no endpoint behavior currently passes both a table ID and an output interface, so the oif argument passed to ip6_pol_route() is always zero and there are no functional changes in this regard.

The ability to read the PHC from user space will be added in the future patch series when adding the actual PTP support.

Implement ndo_hwtstamp_get/set to enable hardware RX timestamping, providing support for SIOC[SG]HWTSTAMP IOCTLs. Included with this support is the small change necessary to read the rx timestamp out of the rx descriptor, now that timestamps start being enabled. The gve clock is only used for hardware timestamps, so started when timestamps are requested and stopped when not needed. This version only supports RX hardware timestamping with the rx filter HWTSTAMP_FILTER_ALL. If the user attempts to configure a more restrictive filter, the filter will be set to HWTSTAMP_FILTER_ALL in the returned structure.

Allow the rx path to recover the high 32 bits of the full 64 bit rx timestamp. Use the low 32 bits of the last synced nic time and the 32 bits of the timestamp provided in the rx descriptor to generate a difference, which is then applied to the last synced nic time to reconstruct the complete 64-bit timestamp. This scheme remains accurate as long as no more than ~2 seconds have passed between the last read of the nic clock and the timestamping application of the received packet.

2025-06-16gve: Add adminq lock for queues creation and destructionZiwei Xiao
Adminq commands for queues creation and destruction were not consistently protected by the driver's adminq_lock. This was previously benign as these operations were always initiated from contexts holding kernel-level locks (e.g., rtnl_lock, netdev_lock), which provided serialization. Upcoming PTP aux_work will issue adminq commands directly from the driver to read the NIC clock, without such kernel lock protection. To prevent race conditions with this new PTP work, this patch ensures the adminq_lock is held during queues creation and destruction.

Breno Leitao says: ==================== netpoll: Untangle netconsole and netpoll Initially netpoll and netconsole were created together, and some functions are in the wrong file. Seperate netconsole-only functions in netconsole, avoiding exports. 1. Expose netpoll logging macros in the public header to enable consistent log formatting across netpoll consumers. 2. Relocate netconsole-specific functions from netpoll to the netconsole module where they are actually used, reducing unnecessary coupling. 3. Remove unnecessary function exports 4. Rename netpoll parsing functions in netconsole to better reflect their specific usage. 5. Create a test to check that cmdline works fine. This was in my todo list since [1], this was a good time to add it here to make sure this patchset doesn't regress. PS: The code was split in a way that it is easy to review. When copying the functions from netpoll to netconsole, I do not change than other than adding `static`. This will make checkpatch unhappy, but, further patches will address the issues. It is done this way to make it easy for reviewers.
