2026-01-15net: usb: dm9601: remove broken SR9700 supportEthan Nelson-Moore
The SR9700 chip sends more than one packet in a USB transaction, like the DM962x chips can optionally do, but the dm9601 driver does not support this mode, and the hardware does not have the DM962x MODE_CTL register to disable it, so this driver drops packets on SR9700 devices. The sr9700 driver correctly handles receiving more than one packet per transaction. While the dm9601 driver could be improved to handle this, the easiest way to fix this issue in the short term is to remove the SR9700 device ID from the dm9601 driver so the sr9700 driver is always used. This device ID should not have been in more than one driver to begin with. The "Fixes" commit was chosen so that the patch is automatically included in all kernels that have the sr9700 driver, even though the issue affects dm9601.

2026-01-15net: usb: sr9700: fix byte numbering in commentsEthan Nelson-Moore
The comments describing the RX/TX headers and status response use a combination of 0- and 1-based indexing, leading to confusion. Correct the numbering and make it consistent. Also fix a typo "pm" for "pn". This issue also existed in dm9601 and was fixed in commit 61189c78bda8 ("dm9601: trivial comment fixes").

2026-01-15usbnet: fix crash due to missing BQL accounting after resumeSimon Schippers
In commit 7ff14c52049e ("usbnet: Add support for Byte Queue Limits (BQL)"), it was missed that usbnet_resume() may enqueue SKBs using __skb_queue_tail() without reporting them to BQL. As a result, the next call to netdev_completed_queue() triggers a BUG_ON() in dql_completed(), since the SKBs queued during resume were never accounted for. This patch fixes the issue by adding a corresponding netdev_sent_queue() call in usbnet_resume() when SKBs are queued after suspend. Because dev->txq.lock is held at this point, no concurrent calls to netdev_sent_queue() from usbnet_start_xmit() can occur. The crash can be reproduced by generating network traffic (e.g. iperf3 -c ... -t 0), suspending the system, and then waking it up (e.g. rtcwake -m mem -s 5). When testing USB2 Android tethering (cdc_ncm), the system crashed within three suspend/resume cycles without this patch. With the patch applied, no crashes were observed after 90 cycles. Testing with an AX88179 USB Ethernet adapter also showed no crashes.

The ADIN1200/ADIN1300 provide a control bit that selects between normal receive termination and the lowest common mode impedance for 100BASE-TX operation. This behavior is controlled through the Low Power Termination register (B_100_ZPTM_EN_DIMRX). Bit 0 of this register enables normal termination when set (this is the default), and selects the lowest common mode impedance when cleared.

QCC2072 is a PCI based device that is very much like WCN7850, the major difference is that QCC2072 has only one phy hence does not support DBS. With previous patches handling such similarity and difference, it is now ready to finally enable supporting this device.

For QCC2072 below REO status descriptors are different compared with QCN9274/WCN7850: hal_reo_get_queue_stats_status hal_reo_flush_queue_status hal_reo_flush_cache_status hal_reo_unblock_cache_status hal_reo_flush_timeout_list_status hal_reo_desc_thresh_reached_status Take hal_reo_get_queue_stats_status as an example: QCC2072: struct hal_reo_get_queue_stats_status_qcc2072 { __le32 tlv32_padding; struct hal_reo_get_queue_stats_status status; } __packed; QCN9274/WCN7850: struct hal_reo_get_queue_stats_status; Besides, QCC2072 has a 32 bits TLV header while QCN9274/WCN7850 has 64. This means that there is no difference between these 3 devices in layout of actual fields, because they all start after a 8 bytes offset QCC2072: { struct hal_tlv_hdr tlv; __le32 tlv32_padding; struct hal_reo_get_queue_stats_status status; } QCN9274/WCN7850: { struct hal_tlv_64_hdr tlv; struct hal_reo_get_queue_stats_status status; } Therefore current implementation luckily works for QCC2072 as well. However it leads to misunderstanding, which should be avoided. So add individual REO status ring handling for QCC2072.

2026-01-15wifi: ath12k: handle REO CMD ring for QCC2072Baochen Qiang
As far as REO CMD ring is concerned, there are two differences between QCC2072 and the existing chips: For the first, the TLV header of ring descriptor for QCC2072 is 32 bits while 64 bits for existing chips. For the second, QCC2072 has different hal_reo_get_queue_stats, hal_reo_flush_cache and hal_reo_update_rx_queue structures. Take hal_reo_get_queue_stats as an example: QCC2072: struct hal_reo_get_queue_stats_qcc2072 { struct hal_reo_cmd_hdr cmd; [...] __le32 rsvd0[6]; } __packed; QCN9274/WCN7850: struct hal_reo_get_queue_stats { struct hal_reo_cmd_hdr cmd; [...] __le32 rsvd0[6]; __le32 tlv64_pad; } __packed; Note there is no tlv64_pad at the end for QCC2072, but all other former fields share the same layout. These make different ring entry size, so that parameter has to be updated with respect to existing chips. This is done in the newly introduced ath12k_hal_srng_create_config_qcc2072() function, which first creates all ring configs by utilizing ath12k_hal_srng_create_config_wcn7850() and then updates the individual field. Besides, the REO command TLV encoding also need to be corrected because of the different TLV bits. This is done by introducing a 32 bit variant for each of the existing 64 bit callback. Note the hal_reo_get_queue_stats_qcc2072 structure is introduced for the purpose of calculating ring entry size. Existing hal_reo_get_queue_stats structure gets used elsewhere even for QCC2072. This is working because the only difference is the tlv64_pad field that is located at the end and not getting used, hence can be ignored.

2026-01-15wifi: ath12k: refactor 320 MHz bandwidth support parsingBaochen Qiang
For single pdev device, 320 MHz bandwidth support is reported only in capability of WMI_HOST_HW_MODE_SINGLE mode, hence commit d4e244c85e45 ("wifi: ath12k: enable 320 MHz bandwidth for 6 GHz band in EHT PHY capability for WCN7850") relaxed the condition check in ath12k_wmi_tlv_mac_phy_caps_ext() to allow SINGLE mode getting parsed in ath12k_wmi_tlv_mac_phy_caps_ext_parse(). Since SINGLE mode is not assumed to be preferred, the function returns unconditionally after parsing 320 MHz support. This works for WCN7850 because it prefers another mode indeed, while it breaks QCC2072 since it prefers SINGLE mode. Due to the unconditional return, the subsequent EHT parsing is skipped. Consequently EHT related features are disabled. Refactor it by moving 320 MHz parsing to ath12k_wmi_tlv_mac_phy_caps_ext(), before the mode checking. This makes the code more straightforward, and work for both WCN7850 and QCC2072.

2026-01-15wifi: ath12k: fix preferred hardware mode calculationBaochen Qiang
For single pdev device like WCN7850/QCC2072, preferred_hw_mode is initialized to WMI_HOST_HW_MODE_SINGLE. Later when firmware sends supported modes to host, each mode is compared with the initial one and if the priority of the new mode is higher, update the parameter and store mode capability. For WCN7850, this does not result in issue, as one of the supported mode indeed has a higher priority. However the only available mode of QCC2072 at this stage is WMI_HOST_HW_MODE_SINGLE, which fails the comparison, hence mode capability is not stored. Subsequently driver initialization fails. Fix it by accepting a mode with the same priority.

2026-01-15wifi: ath11k: move .max_tx_ring to struct ath11k_hw_hal_paramsAlexandru Gagniuc
".max_tx_ring" is an upper bounds to indexing ".tcl2wbm_rbm_map". It is initialized in, core.c, a different file than the array. This spaghetti-like relation is fragile and not obvious. Accidentally setting ".max_tx_ring" too high leads to a hard to track out-of- bounds access and memory corruption. There is a small ambiguity on the meaning of "max_tx_ring": - The highest ring, max=3 implies there are 4 rings (0, 1, 2, 3) - The highest number to use for array indexing (there are 3 rings) Clarify this dependency by moving ".max_tx_ring" adjacent to the array ".tcl2wbm_rbm_map", and name it "num_tx_rings". Use ARRAY_SIZE() instead of #defines to initialize the length field. The intent is to make the code easier to understand rather than fix an existing bug.

pci_set_drvdata() is called twice in ath12k_pci_probe() with the same pointer. Remove the earlier call so drvdata is set after ath12k_base and ath12k_pci initialization is complete. Having two calls might suggest that drvdata needs to be set early for some reason, even though it is not used until after the 'ab' struct ath12k_base is fully populated. Even though exact placement is not critical, keeping a single pci_set_drvdata() at the end of the initialization makes it clearer that drvdata points to a fully initialized structure and avoids confusion for future changes.

2026-01-15net: phy: mscc: macsec: Use new AES library APIEric Biggers
Switch from the old AES library functions (which use struct crypto_aes_ctx) to the new ones (which use struct aes_enckey). This eliminates the unnecessary computation and caching of the decryption round keys. The new AES en/decryption functions are also much faster and use AES instructions when supported by the CPU. Note that in addition to the change in the key preparation function and the key struct type itself, the change in the type of the key struct results in aes_encrypt() (which is temporarily a type-generic macro) calling the new encryption function rather than the old one.

The dev refcount leak in patch #3 is fixed. The first 3 patches are by Oliver Hartkopp and revert the approach to instantly reject unsupported CAN frames introduced in net-next-for-v6.19 and replace it by placing the needed data into the CAN specific ml_priv. The last patch is by Tetsuo Handa and fixes a J1939 refcount leak for j1939_session in session deactivation upon receiving the second RTS. linux-can-fixes-for-6.19-20260115 * tag 'linux-can-fixes-for-6.19-20260115' of git://git.kernel.org/pub/scm/linux/kernel/git/mkl/linux-can: net: can: j1939: j1939_xtp_rx_rts_session_active(): deactivate session upon receiving the second rts can: raw: instantly reject disabled CAN frames can: propagate CAN device capabilities via ml_priv Revert "can: raw: instantly reject unsupported CAN frames" ==================== Link: https://patch.msgid.link/20260115090603.1124860-1-mkl@pengutronix.de Signed-off-by: Paolo Abeni <pabeni@redhat.com>

2026-01-15net/mlx5e: Refine TX timeout handling to skip non-timed-out SQShahar Shitrit
mlx5e_tx_timeout_work() is invoked when the dev_watchdog reports a timed-out TX queue. Currently, the recovery flow is triggered for all stopped SQs, which is not always correct — some SQs may be temporarily stopped without actually timing out. Attempting to recover such SQs results in no EQE being polled (since no real timeout occurred), which the driver misinterprets as a recovery failure, unnecessarily causing channel reopening. Improve the logic to initiate recovery only for SQs that are both stopped and timed out. Utilize the helper introduced in the previous patch to determine whether the netdevice watchdog timeout period has elapsed since the SQ’s last transmit timestamp.
