net: ethernet: mtk_eth_soc: Reset prog ptr to old_prog in case of error in mtk_xdp_setup()

2026-03-12T11:09:58+00:00

[ Upstream commit 0abc73c8a40fd64ac1739c90bb4f42c418d27a5e ] Reset eBPF program pointer to old_prog and do not decrease its ref-count if mtk_open routine in mtk_xdp_setup() fails.

net: ethernet: mtk_eth_soc: fix tx vlan tag for llc packets

2025-09-02T23:27:30+00:00

When sending llc packets with vlan tx offload, the hardware fails to actually add the tag. Deal with this by fixing it up in software.

net: mediatek: wed: Introduce MT7992 WED support to MT7988 SoC

2025-08-14T00:06:55+00:00

Introduce the second WDMA RX ring in WED driver for MT7988 SoC since the Mediatek MT7992 WiFi chipset supports two separated WDMA rings. Add missing MT7988 configurations to properly support WED for MT7992 in MT76 driver.

The reference count to the WED devices has already been incremented when looking them up using of_find_device_by_node() so drop the bogus additional reference taken during probe.

2025-07-19T00:27:47+00:00

Commit cc34acd577f1 ("docs: net: document new locking reality") introduced netif_ vs dev_ function semantics: the former expects locked netdev, the latter takes care of the locking. We don't strictly follow this semantics on either side, but there are more dev_xxx handlers now that don't fit. Rename them to netif_xxx where appropriate. netif_close_many is used only by vlan/dsa and one mtk driver, so move it into NETDEV_INTERNAL namespace.

net: ethernet: mtk_wed: Fix NULL vs IS_ERR() bug in mtk_wed_get_memory_region()

2025-07-18T01:37:14+00:00

We recently changed this from using devm_ioremap() to using devm_ioremap_resource() and unfortunately the former returns NULL while the latter returns error pointers. The check for errors needs to be updated as well.
