From e9553af106a993548445ad373511b503c352090d Mon Sep 17 00:00:00 2001 From: Daniel Golle Date: Fri, 30 Sep 2022 01:56:53 +0100 Subject: [PATCH] net: ethernet: mtk_eth_soc: fix state in __mtk_foe_entry_clear Setting ib1 state to MTK_FOE_STATE_UNBIND in __mtk_foe_entry_clear routine as done by commit 8dbe30da64476a ("net: ethernet: mtk_eth_soc: fix typo in __mtk_foe_entry_clear") breaks flow offloading, at least on older MTK_NETSYS_V1 SoCs, OpenWrt users have confirmed the bug on MT7622 and MT7621 systems. Felix Fietkau suggested to use MTK_FOE_STATE_INVALID instead which works well on both, MTK_NETSYS_V1 and MTK_NETSYS_V2. Tested on MT7622 (Linksys E8450) and MT7986 (BananaPi BPI-R3).
