2025-07-08net: stmmac: Fix interrupt handling for level-triggered mode in DWC_XGMAC2EricChan
According to the Synopsys Controller IP XGMAC-10G Ethernet MAC Databook v3.30a (section 2.7.2), when the INTM bit in the DMA_Mode register is set to 2, the sbd_perch_tx_intr_o[] and sbd_perch_rx_intr_o[] signals operate in level-triggered mode. However, in this configuration, the DMA does not assert the XGMAC_NIS status bit for Rx or Tx interrupt events. This creates a functional regression where the condition if (likely(intr_status & XGMAC_NIS)) in dwxgmac2_dma_interrupt() will never evaluate to true, preventing proper interrupt handling for level-triggered mode. The hardware specification explicitly states that "The DMA does not assert the NIS status bit for the Rx or Tx interrupt events" (Synopsys DWC_XGMAC2 Databook v3.30a, sec. 2.7.2). The fix ensures correct handling of both edge and level-triggered interrupts while maintaining backward compatibility with existing configurations. It has been tested on the hardware device (not publicly available), and it can properly trigger the RX and TX interrupt handling in both the INTM=0 and INTM=2 configurations.

2025-07-08eth: fbnic: Add mailbox support for firmware logsLee Trager
By default firmware will not send logs to the host. This must be explicitly enabled by the driver. The mailbox has the concept of a flag which is a u32 used as a boolean. Lack of flag defaults to a value of false. When enabling logging historical logs may be optionally requested. These are log messages generated by the NIC before the driver was loaded. The driver also sends a log version to support changing the logging format in the future. [SEND_LOGS_REQ] = { [SEND_LOGS] /* flag to request log reporting */ [SEND_LOGS_HISTORY] /* flag to request historical logs */ [SEND_LOGS_VERSION] /* u32 indicating the log format version */ } Logs may be sent to the user either one at a time, or when historical logs are requested in bulk. Firmware may not send more than 14 messages in bulk to prevent flooding the mailbox. [LOG_MSG] = { [LOG_INDEX] /* entry 0 - u64 index of log */ [LOG_MSEC] /* entry 0 - u32 timestamp of log */ [LOG_MSG] /* entry 0 - char log message up to 256 */ [LOG_LENGTH] /* u32 of remaining log items in arrays */ [LOG_INDEX_ARRAY] = { [LOG_INDEX] /* entry 1 - u64 index of log */ [LOG_INDEX] /* entry 2 - u64 index of log */ ... } [LOG_MSEC_ARRAY] = { [LOG_MSEC] /* entry 1 - u32 timestamp of log */ [LOG_MSEC] /* entry 2 - u32 timestamp of log */ ... } [LOG_MSG_ARRAY] = { [LOG_MSG] /* entry 1 - char log message up to 256 */ [LOG_MSG] /* entry 2 - char log message up to 256 */ ... } } Signed-off-by: Lee Trager <lee@trager.us> Reviewed-by: Jacob Keller <jacob.e.keller@intel.com> Link: https://patch.msgid.link/20250702192207.697368-5-lee@trager.us Signed-off-by: Jakub Kicinski <kuba@kernel.org>

Convert mlx5 to dedicated RXFH ops. This is a fairly shallow conversion, TBH, most of the driver code stays as is, but we let the core allocate the context ID for the driver. mlx5e_rx_res_rss_get_rxfh() and friends are made void, since core only calls the driver for context 0. The second call is right after context creation so it must exist (tm). Tested with drivers/net/hw/rss_ctx.py on MCX6.

ICE appears to have some odd form of rss_context use plumbed in for .get_rxfh. The .set_rxfh side does not support creating contexts, however, so this must be dead code. For at least a year now (since commit 7964e7884643 ("net: ethtool: use the tracking array for get_rxfh on custom RSS contexts")) we have not been calling .get_rxfh with a non-zero rss_context. We just get the info from the RSS XArray under dev->ethtool. Remove what must be dead code in the driver, clear the support flags.

2025-07-08eth: otx2: migrate to the *_rxfh_context opsJakub Kicinski
otx2 only supports additional indirection tables (no separate keys etc.) so the conversion to dedicated callbacks and core-allocated context is mostly removing the code which stores the extra tables in the driver. Core already stores the indirection tables for additional contexts, and doesn't call .get for them. One subtle change here is that we'll now start with the table covering all queues, not directing all traffic to queue 0. This is what core expects if the user doesn't pass the initial indir table explicitly (there's a WARN_ON() in the core trying to make sure driver authors don't forget to populate ctx to defaults). Drivers implementing .create_rxfh_context don't have to set cap_rss_ctx_supported, so remove it.

Use the newly added of_reserved_mem_region_to_resource{_byname}() functions to handle "memory-region" properties. The error handling is a bit different for mtk_wed_mcu_load_firmware(). A failed match of the "memory-region-names" would skip the entry, but then other errors in the lookup and retrieval of the address would not skip the entry. However, that distinction is not really important. Either the region is available and usable or it is not. So now, errors from of_reserved_mem_region_to_resource() are ignored so the region is simply skipped.

2025-07-07net/mlx5: HWS, Shrink empty matchersYevgeny Kliteynik
Matcher size is dynamic: it starts at initial size, and then it grows through rehash as more and more rules are added to this matcher. When rules are deleted, matcher's size is not decreased. Rehash approach is greedy. The idea is: if the matcher got to a certain size at some point, chances are - it will get to this size again, so it is better to avoid costly rehash operations whenever possible. However, when all the rules of the matcher are deleted, this should be viewed as special case. If the matcher actually got to the point where it has zero rules, it might be an indication that some usecase from the past is no longer happening. This is where some ICM can be freed. This patch handles this case: when a number of rules in a matcher goes down to zero, the matcher's tables are shrunk to the initial size.

git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/next-queue Tony Nguyen says: ==================== Intel Wired LAN Driver Updates 2025-07-03 Vladimir Oltean converts Intel drivers (ice, igc, igb, ixgbe, i40e) to utilize new timestamping API (ndo_hwtstamp_get() and ndo_hwtstamp_set()). For ixgbe: Paul, Don, Slawomir, and Radoslaw add Malicious Driver Detection (MDD) support for X550 and E610 devices to detect, report, and handle potentially malicious VFs. Simon Horman corrects spelling mistakes. For igbvf: Kohei Enju removes a couple of unreported counters and adds reporting of Tx timeouts. * '10GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/next-queue: igbvf: add tx_timeout_count to ethtool statistics igbvf: remove unused interrupt counter fields from struct igbvf_adapter ixgbe: spelling corrections ixgbe: turn off MDD while modifying SRRCTL ixgbe: add Tx hang detection unhandled MDD ixgbe: check for MDD events ixgbe: add MDD support i40e: convert to ndo_hwtstamp_get() and ndo_hwtstamp_set() ixgbe: convert to ndo_hwtstamp_get() and ndo_hwtstamp_set() igb: convert to ndo_hwtstamp_get() and ndo_hwtstamp_set() igc: convert to ndo_hwtstamp_get() and ndo_hwtstamp_set() ice: convert to ndo_hwtstamp_get() and ndo_hwtstamp_set() ==================== Link: https://patch.msgid.link/20250703174242.3829277-1-anthony.l.nguyen@intel.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>
2025-07-07bng_en: Add a network deviceVikas Gupta
Add a network device with netdev features enabled. Some features are enabled based on the capabilities advertised by the firmware. Add the skeleton of minimal netdev operations. Additionally, initialize the parameters for rings (TX/RX/Completion).

2025-07-07bng_en: Initialize default configurationVikas Gupta
Query resources from the firmware and, based on the availability of resources, initialize the default settings. The default settings include: 1. Rings and other resource reservations with the firmware. This ensures that resources are reserved before network and auxiliary devices are created. 2. Mapping the BAR, which helps access doorbells since its size is known after querying the firmware. 3. Retrieving the TCs and hardware CoS queue mappings.

2025-07-07bng_en: Add resource management supportVikas Gupta
Get the resources and capabilities from the firmware. Add functions to manage the resources with the firmware. These functions will help netdev reserve the resources with the firmware before registering the device in future patches. The resources and their information, such as the maximum available and reserved, are part of the members present in the bnge_hw_resc struct. The bnge_reserve_rings() function also populates the RSS table entries once the RX rings are reserved with the firmware.
