Merge tag 'net-next-7.1' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-nextPull networking updates from Jakub Kicinski: "Core & protocols: - Support HW queue leasing, allowing containers to be granted access to HW queues for zero-copy operations and AF_XDP - Number of code moves to help the compiler with inlining. Avoid output arguments for returning drop reason where possible - Rework drop handling within qdiscs to include more metadata about the reason and dropping qdisc in the tracepoints - Remove the rtnl_lock use from IP Multicast Routing - Pack size information into the Rx Flow Steering table pointer itself. This allows making the table itself a flat array of u32s, thus making the table allocation size a power of two - Report TCP delayed ack timer information via socket diag - Add ip_local_port_step_width sysctl to allow distributing the randomly selected ports more evenly throughout the allowed space - Add support for per-route tunsrc in IPv6 segment routing - Start work of switching sockopt handling to iov_iter - Improve dynamic recvbuf sizing in MPTCP, limit burstiness and avoid buffer size drifting up - Support MSG_EOR in MPTCP - Add stp_mode attribute to the bridge driver for STP mode selection. This addresses concerns about call_usermodehelper() usage - Remove UDP-Lite support (as announced in 2023) - Remove support for building IPv6 as a module. Remove the now unnecessary function calling indirection Cross-tree stuff: - Move Michael MIC code from generic crypto into wireless, it's considered insecure but some WiFi networks still need it Netfilter: - Switch nft_fib_ipv6 module to no longer need temporary dst_entry object allocations by using fib6_lookup() + RCU. Florian W reports this gets us ~13% higher packet rate - Convert IPVS's global __ip_vs_mutex to per-net service_mutex and switch the service tables to be per-net. Convert some code that walks the service lists to use RCU instead of the service_mutex - Add more opinionated input validation to lower security exposure - Make IPVS hash tables to be per-netns and resizable Wireless: - Finished assoc frame encryption/EPPKE/802.1X-over-auth - Radar detection improvements - Add 6 GHz incumbent signal detection APIs - Multi-link support for FILS, probe response templates and client probing - New APIs and mac80211 support for NAN (Neighbor Aware Networking, aka Wi-Fi Aware) so less work must be in firmware Driver API: - Add numerical ID for devlink instances (to avoid having to create fake bus/device pairs just to have an ID). Support shared devlink instances which span multiple PFs - Add standard counters for reporting pause storm events (implement in mlx5 and fbnic) - Add configuration API for completion writeback buffering (implement in mana) - Support driver-initiated change of RSS context sizes - Support DPLL monitoring input frequency (implement in zl3073x) - Support per-port resources in devlink (implement in mlx5) Misc: - Expand the YAML spec for Netfilter Drivers - Software: - macvlan: support multicast rx for bridge ports with shared source MAC address - team: decouple receive and transmit enablement for IEEE 802.3ad LACP "independent control" - Ethernet high-speed NICs: - nVidia/Mellanox: - support high order pages in zero-copy mode (for payload coalescing) - support multiple packets in a page (for systems with 64kB pages) - Broadcom 25-400GE (bnxt): - implement XDP RSS hash metadata extraction - add software fallback for UDP GSO, lowering the IOMMU cost - Broadcom 800GE (bnge): - add link status and configuration handling - add various HW and SW statistics - Marvell/Cavium: - NPC HW block support for cn20k - Huawei (hinic3): - add mailbox / control queue - add rx VLAN offload - add driver info and link management - Ethernet NICs: - Marvell/Aquantia: - support reading SFP module info on some AQC100 cards - Realtek PCI (r8169): - add support for RTL8125cp - Realtek USB (r8152): - support for the RTL8157 5Gbit chip - add 2500baseT EEE status/configuration support - Ethernet NICs embedded and off-the-shelf IP: - Synopsys (stmmac): - cleanup and reorganize SerDes handling and PCS support - cleanup descriptor handling and per-platform data - cleanup and consolidate MDIO defines and handling - shrink driver memory use for internal structures - improve Tx IRQ coalescing - improve TCP segmentation handling - add support for Spacemit K3 - Cadence (macb): - support PHYs that have inband autoneg disabled with GEM - support IEEE 802.3az EEE - rework usrio capabilities and handling - AMD (xgbe): - improve power management for S0i3 - improve TX resilience for link-down handling - Virtual: - Google cloud vNIC: - support larger ring sizes in DQO-QPL mode - improve HW-GRO handling - support UDP GSO for DQO format - PCIe NTB: - support queue count configuration - Ethernet PHYs: - automatically disable PHY autonomous EEE if MAC is in charge - Broadcom: - add BCM84891/BCM84892 support - Micrel: - support for LAN9645X internal PHY - Realtek: - add RTL8224 pair order support - support PHY LEDs on RTL8211F-VD - support spread spectrum clocking (SSC) - Maxlinear: - add PHY-level statistics via ethtool - Ethernet switches: - Maxlinear (mxl862xx): - support for bridge offloading - support for VLANs - support driver statistics - Bluetooth: - large number of fixes and new device IDs - Mediatek: - support MT6639 (MT7927) - support MT7902 SDIO - WiFi: - Intel (iwlwifi): - UNII-9 and continuing UHR work - MediaTek (mt76): - mt7996/mt7925 MLO fixes/improvements - mt7996 NPU support (HW eth/wifi traffic offload) - Qualcomm (ath12k): - monitor mode support on IPQ5332 - basic hwmon temperature reporting - support IPQ5424 - Realtek: - add USB RX aggregation to improve performance - add USB TX flow control by tracking in-flight URBs - Cellular: - IPA v5.2 support"* tag 'net-next-7.1' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next: (1561 commits) net: pse-pd: fix kernel-doc function name for pse_control_find_by_id() wireguard: device: use exit_rtnl callback instead of manual rtnl_lock in pre_exit wireguard: allowedips: remove redundant space tools: ynl: add sample for wireguard wireguard: allowedips: Use kfree_rcu() instead of call_rcu() MAINTAINERS: Add netkit selftest files selftests/net: Add additional test coverage in nk_qlease selftests/net: Split netdevsim tests from HW tests in nk_qlease tools/ynl: Make YnlFamily closeable as a context manager net: airoha: Add missing PPE configurations in airoha_ppe_hw_init() net: airoha: Fix VIP configuration for AN7583 SoC net: caif: clear client service pointer on teardown net: strparser: fix skb_head leak in strp_abort_strp() net: usb: cdc-phonet: fix skb frags[] overflow in rx_complete() selftests/bpf: add test for xdp_master_redirect with bond not up net, bpf: fix null-ptr-deref in xdp_master_redirect() for down master net: airoha: Remove PCE_MC_EN_MASK bit in REG_FE_PCE_CFG configuration sctp: disable BH before calling udp_tunnel_xmit_skb() sctp: fix missing encap_port propagation for GSO fragments net: airoha: Rely on net_device pointer in ETS callbacks ...

Merge branch 'dpll-zl3073x-refactor-state-management'Ivan Vecera says:====================dpll: zl3073x: refactor state managementThis series refactors the zl3073x DPLL driver to centralize hardwarestate management behind dedicated per-module state interfaces, replacingscattered direct register accesses in dpll.c with cached state andproper accessor functions.The driver already uses a fetch/get/set pattern for ref, out, and synthmodules. This series extends and refines that pattern:First, struct_group() is applied to the existing ref, out, and synthstructures to partition fields into cfg (mutable configuration), inv(invariants set at init), and stat (read-only status) groups. Thisenables group-level memcmp for short-circuit checks and bulk copies instate_set, and adds invariant validation guards.A ref_state_update() helper is extracted to encapsulate the per-referencemonitor status register read, keeping direct register access behind theref module interface.A new zl3073x_chan module is introduced following the same pattern,caching the DPLL channel mode_refsel register with inline getters andsetters. The refsel_mode and forced_ref fields are removed from structzl3073x_dpll in favor of the cached channel state.The chan module is then extended with cached mon_status and refsel_statusregisters, converting lock_status_get and selected_ref_get from directHW reads to cached state lookups refreshed by the periodic worker.Reference priority registers are cached in the chan cfg group, removingthe ad-hoc ref_prio_get/set functions and the redundant pin->selectableflag, which is now derived from the cached priority. Theselected_ref_set function is inlined into input_pin_state_on_dpll_set,unifying all mode paths through a single chan_state_set commit point.Finally, selected_ref_get is dropped entirely since the refsel_statusregister provides the selected reference regardless of mode, andconnected_ref_get is simplified to a direct refsel_state check.====================Link: https://patch.msgid.link/20260315174224.399074-1-ivecera@redhat.comSigned-off-by: Jakub Kicinski List of files: /linux/drivers/dpll/zl3073x/chan.c

Sun, 15 Mar 2026 18:42:23 +0100

dpll: zl3073x: add reference priority to zl3073x_chanCache the ZL_REG_DPLL_REF_PRIO registers in the zl3073x_chan cfg group.These mailbox-based registers store per-reference priority values(4 bits each, P/N packed) used for automatic reference selection.Add ref_prio[] array to struct zl3073x_chan and provide inline helperszl3073x_chan_ref_prio_get(), zl3073x_chan_ref_prio_set(), andzl3073x_chan_ref_is_selectable() for nibble-level access and priorityqueries. Extend state_fetch and state_set with DPLL mailbox operationsto read and write the priority registers.Replace the ad-hoc zl3073x_dpll_ref_prio_get/set functions in dpll.cwith the cached state pattern, removing direct mailbox access fromthe DPLL layer. This also simplifies pin registration since readingpriority from cached state cannot fail.Remove the pin->selectable flag from struct zl3073x_dpll_pin andderive the selectable state from the cached ref priority viazl3073x_chan_ref_is_selectable(), eliminating a redundant cache.Inline zl3073x_dpll_selected_ref_set() intozl3073x_dpll_input_pin_state_on_dpll_set(), unifying all manual andautomatic mode paths to commit changes through a singlezl3073x_chan_state_set() call at the end of the function.Move hardware limit constants from core.h to regs.h so that chan.hcan reference ZL3073X_NUM_REFS for the ref_prio array size.Signed-off-by: Ivan Vecera Link: https://patch.msgid.link/20260315174224.399074-6-ivecera@redhat.comSigned-off-by: Jakub Kicinski List of files: /linux/drivers/dpll/zl3073x/chan.c

dpll: zl3073x: add DPLL channel status fields to zl3073x_chanAdd mon_status and refsel_status fields to struct zl3073x_chan in astat group to cache the 'dpll_mon_status' and 'dpll_refsel_status'registers.Add zl3073x_chan_lock_state_get(), zl3073x_chan_is_ho_ready(),zl3073x_chan_refsel_state_get() and zl3073x_chan_refsel_ref_get()inline helpers for reading cached state, and zl3073x_chan_state_update()for refreshing both registers from hardware. Call it fromzl3073x_chan_state_fetch() as well so that channel status isinitialized at device startup.Call zl3073x_dev_chan_states_update() from the periodic work tokeep the cached state up to date and convertzl3073x_dpll_lock_status_get() and zl3073x_dpll_selected_ref_get()to use the cached state via the new helpers instead of direct registerreads.Signed-off-by: Ivan Vecera Link: https://patch.msgid.link/20260315174224.399074-5-ivecera@redhat.comSigned-off-by: Jakub Kicinski List of files: /linux/drivers/dpll/zl3073x/chan.c

3032e95987fa0da656ce3a5eb454674e7cc60a12 - dpll: zl3073x: introduce zl3073x_chan for DPLL channel state

Sun, 15 Mar 2026 18:42:21 +0100

dpll: zl3073x: introduce zl3073x_chan for DPLL channel stateExtract DPLL channel state management into a dedicated zl3073x_chanmodule, following the pattern already established by zl3073x_ref,zl3073x_out and zl3073x_synth.The new struct zl3073x_chan caches the raw mode_refsel register valuein a cfg group with inline getters and setters to extract and updatethe bitfields. Three standard state management functions are provided: - zl3073x_chan_state_fetch: read the mode_refsel register from HW - zl3073x_chan_state_get: return cached channel state - zl3073x_chan_state_set: write changed state to HW, skip if unchangedThe channel state array chan[ZL3073X_MAX_CHANNELS] is added to structzl3073x_dev. Channel state is fetched as part ofzl3073x_dev_state_fetch, using the chip-specific channel count.The refsel_mode and forced_ref fields are removed from structzl3073x_dpll and all direct register accesses in dpll.c are replacedwith the new chan state operations.Signed-off-by: Ivan Vecera Link: https://patch.msgid.link/20260315174224.399074-4-ivecera@redhat.comSigned-off-by: Jakub Kicinski List of files: /linux/drivers/dpll/zl3073x/chan.c
