net: sfp: add quirks for Hisense and HSGQ GPON ONT SFP modules

2026-04-08T01:13:51+00:00

Several GPON ONT SFP sticks based on Realtek RTL960x report 1000BASE-LX at 1300MBd in their EEPROM but can operate at 2500base-X. On hosts capable of 2500base-X (e.g. Banana Pi R3 / MT7986), the kernel negotiates only 1G because it trusts the incorrect EEPROM data. Add quirks for: - Hisense-Leox LXT-010S-H - Hisense ZNID-GPON-2311NA - HSGQ HSGQ-XPON-Stick Each quirk advertises 2500base-X and ignores TX_FAULT during the module's ~40s Linux boot time. Tested on Banana Pi R3 (MT7986) with OpenWrt 25.12.1, confirmed 2.5Gbps link and full throughput with flow offloading.

net: sfp: Fix Ubiquiti U-Fiber Instant SFP module on mvneta

2026-03-28T03:55:52+00:00

In commit 8110633db49d7de2 ("net: sfp-bus: allow SFP quirks to override Autoneg and pause bits") we moved the setting of Autoneg and pause bits before the call to SFP quirk when parsing SFP module support. Since the quirk for Ubiquiti U-Fiber Instant SFP module zeroes the support bits and sets 1000baseX_Full only, the above mentioned commit changed the overall computed support from 1000baseX_Full, Autoneg, Pause, Asym_Pause to just 1000baseX_Full. This broke the SFP module for mvneta, which requires Autoneg for 1000baseX since commit c762b7fac1b249a9 ("net: mvneta: deny disabling autoneg for 802.3z modes"). Fix this by setting back the Autoneg, Pause and Asym_Pause bits in the quirk.

net: sfp: improve Huawei MA5671a fixup

2026-03-10T01:46:46+00:00

With the current sfp_fixup_ignore_tx_fault() fixup we ignore the TX_FAULT signal, but we also need to apply sfp_fixup_ignore_los() in order to be able to communicate with the module even if the fiber isn't connected for configuration purposes. This is needed for all the MA5671a firmwares, excluding the FS modded firmware.

treewide: Replace kmalloc with kmalloc_obj for non-scalar types

2026-02-21T09:02:28+00:00

This is the result of running the Coccinelle script from scripts/coccinelle/api/kmalloc_objs.cocci. The script is designed to avoid scalar types (which need careful case-by-case checking), and instead replace kmalloc-family calls that allocate struct or union object instances: Single allocations: kmalloc(sizeof(TYPE), ...) are replaced with: kmalloc_obj(TYPE, ...) Array allocations: kmalloc_array(COUNT, sizeof(TYPE), ...) are replaced with: kmalloc_objs(TYPE, COUNT, ...) Flex array allocations: kmalloc(struct_size(PTR, FAM, COUNT), ...) are replaced with: kmalloc_flex(*PTR, FAM, COUNT, ...) (where TYPE may also be *VAR) The resulting allocations no longer return "void *", instead returning "TYPE *". Signed-off-by: Kees Cook

net: sfp: Fix quirk for Ubiquiti U-Fiber Instant SFP module

2026-01-31T01:19:37+00:00

Commit fd580c9830316eda ("net: sfp: augment SFP parsing with phy_interface_t bitmap") did not add augumentation for the interface bitmap in the quirk for Ubiquiti U-Fiber Instant. The subsequent commit f81fa96d8a6c7a77 ("net: phylink: use phy_interface_t bitmaps for optical modules") then changed phylink code for selection of SFP interface: instead of using link mode bitmap, the interface bitmap is used, and the fastest interface mode supported by both SFP module and MAC is chosen. Since the interface bitmap contains also modes faster than 1000base-x, this caused a regression wherein this module stopped working out-of-the-box. Fix this.

net: sfp: add quirk for Lantech 8330-265D

2026-01-30T03:39:56+00:00

Similar to Lantech 8330-262D-E, the Lantech 8330-265D also reports 2500MBd instead of 3125MBd. Also, all 8330-265D report normal RX_LOS in EEPROM, but some signal inverted RX_LOS. We therefore need to ignore RX_LOS on these modules. Signed-off-by: Marek Behún Link: https://patch.msgid.link/20260128170044.15576-1-kabel@kernel.org Signed-off-by: Jakub Kicinski

net: sfp: return the number of written bytes for smbus single byte access

2026-01-07T01:13:34+00:00

We expect the SFP write accessors to return the number of written bytes. We fail to do so for single-byte smbus accesses, which may cause errors when setting a module's high-power state and for some cotsworks modules. Let's return the amount of written bytes, as expected.
