Merge branch 'intel-wired-lan-update-2026-04-27-ice-iavf'
Jacob Keller says: ==================== Intel Wired LAN Update 2026-04-27 (ice, iavf) Petr Oros from RedHat has accumulated a number of fixes for the Intel ice and iavf drivers, bundled together in this series. First, a series of 4 fixes to resolve issues with the iavf driver logic for handling VLAN filters. This includes keeping VLAN filters while the interface is brought down, waiting for confirmation on filter deletion before deleting filters from the driver tracking structures, and handling the VIRTCHNL_OP_ADD_VLAN for the old v1 VLAN_ADD command. A fix for a crash in ice_reset_all_vfs(), properly checking for errors when ice_vf_rebuild_vsi() fails. A fix for a possible infinite recursion in ice_cfg_tx_topo() that occurs when trying to apply invalid Tx topology configuration. A fix to initialize the SMA pins in the DPLL subsystem properly. A fix to change the SMA and U.FL pin state for paired pins, ensuring that all flows changing one pin will also update its shared pin appropriately. A preparatory patch to export __dpll_pin_change_ntf() so that drivers can notify pin changes while already holding the dpll_lock. A fix to ensure DPLL notifications are sent for the software-controlled pins which wrap the physical CGU input/output pins. A fix to add DPLL notifications for peer pins when changing the SMA or U.FL pins, ensuring DPLL subsystem is notified about the paired connected pins.
