2025-01-16net: phylink: add phylink_link_is_up() helperRussell King (Oracle)
Add a helper to determine whether the link is up or down. Currently this is only used in one location, but becomes necessary to test when reconfiguring EEE.

2025-01-16net: phy: add support for querying PHY clock stop capabilityRussell King (Oracle)
Add support for querying whether the PHY allows the transmit xMII clock to be stopped while in LPI mode. This will be used by phylink to pass to the MAC driver so it can configure the generation of the xMII clock appropriately.

2025-01-16clk: analogbits: Fix incorrect calculation of vco rate deltaBo Gan
In wrpll_configure_for_rate() we try to determine the best PLL configuration for a target rate. However, in the loop where we try values of R, we should compare the derived `vco` with `target_vco_rate`. However, we were in fact comparing it with `target_rate`, which is actually after Q shift. This is incorrect, and sometimes can result in suboptimal clock rates. Fix it.

2025-01-16ice: support FW Recovery ModeKonrad Knitter
Recovery Mode is intended to recover from a fatal failure scenario in which the device is not accessible to the host, meaning the firmware is non-responsive. The purpose of the Firmware Recovery Mode is to enable software tools to update firmware and/or device configuration so the fatal error can be resolved. Recovery Mode Firmware supports a limited set of admin commands required for NVM update. Recovery Firmware does not support hardware interrupts so a polling mode is used. The driver will expose only the minimum set of devlink commands required for the recovery of the adapter. Using an appropriate NVM image, the user can recover the adapter using the devlink flash API. Prior to 4.20 E810 Adapter Recovery Firmware supports only the update and erase of the "fw.mgmt" component. E810 Adapter Recovery Firmware doesn't support selected preservation of cards settings or identifiers. The following command can be used to recover the adapter: $ devlink dev flash <pci-address> <update-image.bin> component fw.mgmt overwrite settings overwrite identifier Newer FW versions (4.20 or newer) supports update of "fw.undi" and "fw.netlist" components. $ devlink dev flash <pci-address> <update-image.bin> Tested on Intel Corporation Ethernet Controller E810-C for SFP FW revision 3.20 and 4.30.

2025-01-16wifi: brcmfmac: fix NULL pointer dereference in brcmf_txfinalize()Marcel Hamer
On removal of the device or unloading of the kernel module a potential NULL pointer dereference occurs. The following sequence deletes the interface: brcmf_detach() brcmf_remove_interface() brcmf_del_if() Inside the brcmf_del_if() function the drvr->if2bss[ifidx] is updated to BRCMF_BSSIDX_INVALID (-1) if the bsscfgidx matches. After brcmf_remove_interface() call the brcmf_proto_detach() function is called providing the following sequence: brcmf_detach() brcmf_proto_detach() brcmf_proto_msgbuf_detach() brcmf_flowring_detach() brcmf_msgbuf_delete_flowring() brcmf_msgbuf_remove_flowring() brcmf_flowring_delete() brcmf_get_ifp() brcmf_txfinalize() Since brcmf_get_ip() can and actually will return NULL in this case the call to brcmf_txfinalize() will result in a NULL pointer dereference inside brcmf_txfinalize() when trying to update ifp->ndev->stats.tx_errors. This will only happen if a flowring still has an skb. Although the NULL pointer dereference has only been seen when trying to update the tx statistic, all other uses of the ifp pointer have been guarded as well with an early return if ifp is NULL.

Generalize pcie_read_tlp_log() and struct pcie_tlp_log to also handle TLP Prefix Log. The relevant registers are formatted identically in AER and DPC Capability, but has these variations: a) The offsets of TLP Prefix Log registers vary. b) DPC RP PIO TLP Prefix Log register can be < 4 DWORDs. c) AER TLP Prefix Log Present (PCIe r6.1 sec 7.8.4.7) can indicate Prefix Log is not present. Therefore callers must pass the offset of the TLP Prefix Log register and the entire length to pcie_read_tlp_log() to be able to read the correct number of TLP Prefix DWORDs from the correct offset.
