This driver supports Applied Micro Circuits Corporation QT2025 PHY, based on a driver for Tehuti Networks TN40xx chips. The original driver for TN40xx chips supports multiple PHY hardware (AMCC QT2025, TI TLK10232, Aqrate AQR105, and Marvell 88X3120, 88X3310, and MV88E2010). This driver is extracted from the original driver and modified to a PHY driver in Rust. This has been tested with Edimax EN-9320SFP+ 10G network adapter. Reviewed-by:

Add unified genphy_read_status function for C22 and C45 registers. Instead of having genphy_c22 and genphy_c45 methods, this unifies genphy_read_status functions for C22 and C45. Reviewed-by:

Add the unified read/write API for C22 and C45 registers. The abstractions support access to only C22 registers now. Instead of adding read/write_c45 methods specifically for C45, a new reg module supports the unified API to access C22 and C45 registers with trait, by calling an appropriate phylib functions.

Michael Chan says: ==================== bnxt_en: Update for net-next This series starts with 2 patches to support firmware crash dump. The driver allocates the required DMA memory ahead of time for firmware to store the crash dump if and when it crashes. Patch 3 adds priority and TPID for the .ndo_set_vf_vlan() callback. Note that this was rejected and reverted last year and it is being re-submitted after recent changes in the guidelines. The remaining patches are MSIX related. Legacy interrupt is no longer supported by firmware so we remove the support in the driver. We then convert to use the newer kernel APIs to allocate and enable MSIX vectors. The last patch adds support for dynamic MSIX. v3: https://lore.kernel.org/20240823195657.31588-1-michael.chan@broadcom.com v2: https://lore.kernel.org/20240816212832.185379-1-michael.chan@broadcom.com v1: https://lore.kernel.org/20240713234339.70293-1-michael.chan@broadcom.com ==================== Link: https://patch.msgid.link/20240828183235.128948-1-michael.chan@broadcom.comSigned-off-by:

A range of MSIX vectors are allocated at initialization for the number needed for RocE and L2. During run-time, if the user increases or decreases the number of L2 rings, all the MSIX vectors have to be freed and a new range has to be allocated. This is not optimal and causes disruptions to RoCE traffic every time there is a change in L2 MSIX. If the system supports dynamic MSIX allocations, use dynamic allocation to add new L2 MSIX vectors or free unneeded L2 MSIX vectors. RoCE traffic is not affected using this scheme. Reviewed-by:

If dynamic MSIX allocation is supported, additional MSIX can be allocated at run-time without reinitializing the existing MSIX entries. The first step to support this dynamic scheme is to allocate a large enough bp->irq_tbl if dynamic allocation is supported. Reviewed-by:

Firmware has deprecated support for legacy INTX in 2022 (since v2.27) and INTX hasn't been tested for many years before that. INTX was only used as a fallback mechansim in case MSIX wasn't available. MSIX is always supported by all firmware. If MSIX capability in PCI config space is not found during probe, abort. Reviewed-by:

In case of im_protocols value is 1 and tm_protocols value is 0 this combination successfully passes the check 'if (!im_protocols && !tm_protocols)' in the nfc_start_poll(). But then after pn533_poll_create_mod_list() call in pn533_start_poll() poll mod list will remain empty and dev->poll_mod_count will remain 0 which lead to division by zero. Normally no im protocol has value 1 in the mask, so this combination is not expected by driver. But these protocol values actually come from userspace via Netlink interface (NFC_CMD_START_POLL operation). So a broken or malicious program may pass a message containing a "bad" combination of protocol parameter values so that dev->poll_mod_count is not incremented inside pn533_poll_create_mod_list(), thus leading to division by zero. Call trace looks like: nfc_genl_start_poll() nfc_start_poll() ->start_poll() pn533_start_poll() Add poll mod list filling check. Found by Linux Verification Center (linuxtesting.org) with SVACE.
