Hangbin Liu says: ==================== Doc: update bridge doc The current bridge kernel doc is too old. It only pointed to the linuxfoundation wiki page which lacks of the new features. Here let's start the new bridge document and put all the bridge info so new developers and users could catch up the last bridge status soon. v3 -> v4: - Patch01: Reference and borrow definitions from the IEEE 802.1Q-2022 standard for bridge (Stephen Hemminger) - Patch04: Remind that kAPI is unstable. Add back sysfs part, but only note that sysfs is deprecated. (Stephen Hemminger, Florian Fainelli) - Patch05: Mention the RSTP and IEEE 802.1D developing info. (Stephen Hemminger) - Some other grammar fixes. v2 -> v3: - Split the bridge doc update and adding kAPI/uAPI field to 2 part (Nikolay Aleksandrov) - Update bridge and bridge enum descriptions (Nikolay Aleksandrov) - Add user space stp help for STP doc (Vladimir Oltean) v1 -> v2: - Update bridge and bridge port enum descriptions (Vladimir Oltean) RFCv3 -> v1: - Fix up various typos, grammar and technical issues (Nikolay Aleksandrov) RFCv2 -> RFCv3: - Update netfilter part (Florian Westphal) - Break the one large patch in to multiparts for easy reviewing. Please tell me if I break it too much.. (Nikolay Aleksandrov) - Update the description of each enum and doc (Nikolay Aleksandrov) - Add more descriptions for STP/Multicast/VLAN. RFCv1 -> RFCv2: - Drop the python tool that generate iproute man page from kernel doc ==================== Link: https://lore.kernel.org/r/20231201081951.1623069-1-liuhangbin@gmail.comSigned-off-by:Paolo Abeni <pabeni@redhat.com>

Refactor EST implementation by moving common code for DWMAC4 and DWXGMAC IPs into a separate EST module. EST implementation for DWMAC4 and DWXGMAC differs only for CSR base address, PTOV field offset width, and PTOV clock multiplier value. Thanks, Serge Semin and Jakub Kicinski for the suggestions on refactoring EST implementation into a separate EST module. Signed-off-by:

Enabled the following EST related interrupts: 1) Constant Gate Control Error (CGCE) 2) Head-of-Line Blocking due to Scheduling (HLBS) 3) Head-of-Line Blocking due to Frame Size (HLBF) 4) Base Time Register error (BTRE) 5) Switch to S/W owned list Complete (SWLC) Also, add EST errors into the ethtool statistic. The commit e49aa315 ("net: stmmac: EST interrupts handling and error reporting") and commit 9f298959 ("net: stmmac: Add EST errors into ethtool statistic") add EST interrupts handling and error reporting support to DWMAC4 core. This patch enables the same support for XGMAC. Signed-off-by:

Amritha Nambiar says: ==================== Introduce queue and NAPI support in netdev-genl (Was: Introduce NAPI queues support) Add the capability to export the following via netdev-genl interface: - queue information supported by the device - NAPI information supported by the device Introduce support for associating queue and NAPI instance. Extend the netdev_genl generic netlink family for netdev with queue and NAPI data. The queue parameters exposed are: - queue index - queue type - ifindex - NAPI id associated with the queue Additional rx and tx queue parameters can be exposed in follow up patches by stashing them in netdev queue structures. XDP queue type can also be supported in future. The NAPI fields exposed are: - NAPI id - NAPI device ifindex - Interrupt number associated with the NAPI instance - PID for the NAPI thread This series only supports 'get' ability for retrieving certain queue and NAPI attributes. The 'set' ability for configuring queue and associated NAPI instance via netdev-genl will be submitted as a separate patch series.

Michael Chan says: ==================== bnxt_en: Support new 5760X P7 devices This series completes the basic support for the new 5760X P7 devices with new PCI IDs added in the last patch. Thie first patch fixes a backing store issue introduced in the last patchset last week. The 2nd patch is the new firmware interface required to support the new chips. The next few patches are doorbell changes, refactoring, and new hardware interface structures. New changes to support packet reception including TPA are added in patch 10. The next 4 patches are ethernet link related changes to support the new chip. ==================== Link: https://lore.kernel.org/r/20231201223924.26955-1-michael.chan@broadcom.comSigned-off-by:

Refactor bnxt_tpa_start() by adding bnxt_tpa_metadata() to gather the metadata from the TPA_START completion. This makes it easier to support the new P7 chip which has a modified TPA_START completion structure with different metadata formats. We also add vlan_valid and cfa_code_valid fields to the bnxt_tpa_info structure so that the VLAN and VF rep logic can be common for all chips. The VLAN metadata is now collected in bnxt_tpa_start() only when it is valid and the vlan_valid field will be set. bnxt_tpa_end() can now use common VLAN logic for all chips. Signed-off-by:

The new chip family passes the Toggle bits to the driver in the NQE notification. The driver now stores this value and sends it back to hardware when it re-arms the RX and TX CQs. Together with the earlier patch that guarantees the driver will only re-arm the CQ at the end of NAPI polling if it has seen a new NQE, this method allows the hardware to detect any dropped doorbells.
