2025-09-08net: dsa: b53: fix ageing time for BCM53101Jonas Gorski

2025-09-08idpf: add support for XDP on RxAlexander Lobakin
Use libeth XDP infra to support running XDP program on Rx polling. This includes all of the possible verdicts/actions. XDP Tx queues are cleaned only in "lazy" mode when there are less than 1/4 free descriptors left on the ring. libeth helper macros to define driver-specific XDP functions make sure the compiler could uninline them when needed. Use __LIBETH_WORD_ACCESS to parse descriptors more efficiently when applicable. It really gives some good boosts and code size reduction on x86_64: XDP only: add/remove: 0/0 grow/shrink: 3/3 up/down: 5/-59 (-54) with XSk: add/remove: 0/0 grow/shrink: 5/6 up/down: 23/-124 (-101) with the most demanding workloads like XSk xmit differing in up to 5-8%.

2025-09-08idpf: use generic functions to build xdp_buff and skbAlexander Lobakin
In preparation of XDP support, move from having skb as the main frame container during the Rx polling to &xdp_buff. This allows to use generic and libeth helpers for building an XDP buffer and changes the logics: now we try to allocate an skb only when we processed all the descriptors related to the frame. Store &libeth_xdp_stash instead of the skb pointer on the Rx queue. It's only 8 bytes wider, but contains everything we may need.

Extend basic structures of the driver (e.g. 'idpf_vport', 'idpf_*_queue', 'idpf_vport_user_config_data') by adding members necessary to support XDP. Add extra XDP Tx queues needed to support XDP_TX and XDP_REDIRECT actions without interfering with regular Tx traffic. Also add functions dedicated to support XDP initialization for Rx and Tx queues and call those functions from the existing algorithms of queues configuration.

2025-09-08idpf: add support for nointerrupt queuesAlexander Lobakin
Currently, queues are associated 1:1 with interrupt vectors as it's assumed queues are always interrupt-driven. For XDP, we want to use Tx queues without interrupts and only do "lazy" cleaning when the number of free elements is <= threshold (closest pow-2 to 1/4 of the ring). In order to use a queue without an interrupt, idpf still needs to have a vector assigned to it to flush descriptors. This vector can be global and only one for the whole vport to handle all its noirq queues. Always request one excessive vector and configure it in non-interrupt mode right away when creating vport, so that it can be used later by queues when needed (not only XDP ones).

2025-09-08idpf: remove SW marker handling from NAPIMichal Kubiak
SW marker descriptors on completion queues are used only when a queue is about to be destroyed. It's far from hotpath and handling it in the hotpath NAPI poll makes no sense. Instead, run a simple poller after a virtchnl message for destroying the queue is sent and wait for the replies. If replies for all of the queues are received, this means the synchronization is done correctly and we can go forth with stopping the link.

In the queue-based scheduling mode, Tx completion descriptor is 4 bytes comparing to 8 bytes in flow-based. Add definition for it and allocate the corresponding amount of memory for the descriptors during the completion queue creation. This does not include handling 4-byte completions during Tx polling, as for now, the only user of QB will be XDP, which has its own routines.

2025-09-08idpf: link NAPIs to queuesAlexander Lobakin
Add the missing linking of NAPIs to netdev queues when enabling interrupt vectors in order to support NAPI configuration and interfaces requiring get_rx_queue()->napi to be set (like XSk busy polling). As currently, idpf_vport_{start,stop}() is called from several flows with inconsistent RTNL locking, we need to synchronize them to avoid runtime assertions. Notably: * idpf_{open,stop}() -- regular NDOs, RTNL is always taken; * idpf_initiate_soft_reset() -- usually called under RTNL; * idpf_init_task -- called from the init work, needs RTNL; * idpf_vport_dealloc -- called without RTNL taken, needs it. Expand common idpf_vport_{start,stop}() to take an additional bool telling whether we need to manually take the RTNL lock.

2025-09-08idpf: use a saner limit for default number of queues to allocateAlexander Lobakin
Currently, the maximum number of queues available for one vport is 16. This is hardcoded, but then the function calculating the optimal number of queues takes min(16, num_online_cpus()). In order to be able to allocate more queues, which will be then used for XDP, stop hardcoding 16 and rely on what the device gives us[*]. Instead of num_online_cpus(), which is considered suboptimal since at least 2013, use netif_get_num_default_rss_queues() to still have free queues in the pool. [*] With the note: Currently, idpf always allocates `IDPF_MAX_BUFQS_PER_RXQ_GRP` (== 2) buffer queues for each Rx queue and one completion queue for each Tx for best performance. But there was no check whether such number is available, IOW the assumption was not backed by any "harmonizing" / actual checks. Fix this while at it. nr_cpu_ids number of Tx queues are needed only for lockless XDP sending, the regular stack doesn't benefit from that anyhow. On a 128-thread Xeon, this now gives me 32 regular Tx queues and leaves 224 free for XDP (128 of which will handle XDP_TX, .ndo_xdp_xmit(), and XSk xmit when enabled). Note 2: Unfortunately, some CP/FW versions are not able to reconfigure/enable/disable large amount of queues within the minimum timeout (2 seconds). For now, fall back to the default timeout for every operation until this is resolved.

2025-09-08idpf: fix Rx descriptor ready check barrier in splitqAlexander Lobakin
No idea what the current barrier position was meant for. At that point, nothing is read from the descriptor, only the pointer to the actual one is fetched. The correct barrier usage here is after the generation check, so that only the first qword is read if the descriptor is not yet ready and we need to stop polling. Debatable on coherent DMA as the Rx descriptor size is <= cacheline size, but anyway, the current barrier position only makes the codegen worse.

When buf_len is not 4-byte aligned in ath12k_wmi_mgmt_send(), the firmware asserts and triggers a recovery. The following error messages are observed: ath12k_pci 0004:01:00.0: failed to submit WMI_MGMT_TX_SEND_CMDID cmd ath12k_pci 0004:01:00.0: failed to send mgmt frame: -108 ath12k_pci 0004:01:00.0: failed to tx mgmt frame, vdev_id 0 :-108 ath12k_pci 0004:01:00.0: waiting recovery start... This issue was observed when running 'iw wlanx set power_save off/on' in MLO station mode, which triggers the sending of an SMPS action frame with a length of 27 bytes to the AP. To resolve the misalignment, use buf_len_aligned instead of buf_len when constructing the WMI TLV header.

Commit afbab6e4e88d ("wifi: ath12k: modify ath12k_mac_op_bss_info_changed() for MLO") replaced the bss_info_changed() callback with vif_cfg_changed() and link_info_changed() to support Multi-Link Operation (MLO). As a result, the station power save configuration is no longer correctly applied in ath12k_mac_bss_info_changed(). Move the handling of 'BSS_CHANGED_PS' into ath12k_mac_op_vif_cfg_changed() to align with the updated callback structure introduced for MLO, ensuring proper power-save behavior for station interfaces.
