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

2025-09-09T17:02:25Z

[ Upstream commit d4736737110ffa83d29f1c5d17b26113864205f6 ] 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: mtk_eth_soc: fix device leak at probe

commit 3e13274ca8750823e8b68181bdf185d238febe0d upstream. 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.

driver: net: ethernet: mtk_star_emac: fix suspend/resume issue

2025-05-29T10:22:25Z

Identify the cause of the suspend/resume hang: netif_carrier_off() is called during link state changes and becomes stuck while executing linkwatch_work(). To resolve this issue, call netif_device_detach() during the Ethernet suspend process to temporarily detach the network device from the kernel and prevent the suspend/resume hang.

net: ethernet: mtk_eth_soc: fix typo for declaration MT7988 ESW capability

2025-05-15T02:28:21Z

Since MTK_ESW_BIT is a bit number rather than a bitmap, it causes MTK_HAS_CAPS to produce incorrect results. This leads to the ETH driver not declaring MAC capabilities correctly for the MT7988 ESW.

net: ethernet: mtk_eth_soc: do not reset PSE when setting FE

Remove redundant PSE reset. When setting FE register there is no need to reset PSE, doing so may cause FE to work abnormal.

net: ethernet: mtk_eth_soc: reset all TX queues on DMA free

2025-05-06T11:37:34Z

The purpose of resetting the TX queue is to reset the byte and packet count as well as to clear the software flow control XOFF bit. MediaTek developers pointed out that netdev_reset_queue would only resets queue 0 of the network device. Queues that are not reset may cause unexpected issues. Packets may stop being sent after reset and "transmit timeout" log may be displayed. Import fix from MediaTek's SDK to resolve this issue.
