From bade0d238b60c29dafcc7da17501fa489495d6ae Mon Sep 17 00:00:00 2001 From: Zhi-Jun You Date: Wed, 15 Jul 2026 23:21:13 +0800 Subject: wifi: mt76: mt7915: fix net_fill_forward_path for non-DBDC mt7986 Current implementation assumes that the hardware supports DBDC or single band and binds to band0. This causes net_fill_forward_path to select the wrong queue for non-DBDC mt7986 because it binds to band1 and getting the following in dmesg: ieee80211 phy2: WA: --> drop by reaseon:1, msdu id = 0xc002 but failed! mtk_wed1: error status=00000002 ieee80211 phy2: WA: txblk 10324e00 len = 128 DW0 : 10 00 00 00 DW1 : 00 00 00 00 DW2 : 00 00 00 00 DW3 : 72 0f 94 68 DW4 : 00 00 00 00 DW5 : ff 03 00 00 DW6 : 00 00 3c 40 DW7 : 00 17 dd 14 DW8 : 79 6f 00 00 DW9 : 02 c0 00 00 DW10 : 58 c5 34 10 DW11 : 00 00 00 00 DW12 : 00 06 3e 00 DW13 : 00 00 00 80 DW14 : 10 8c 00 00 DW15 : 00 00 00 00 DW16 : 00 00 00 00 DW17 : 00 00 00 00 DW18 : 00 00 00 00 DW19 : 00 00 00 00 DW20 : 00 00 00 00 DW21 : 00 00 00 00 DW22 : 00 00 00 00 DW23 : 00 00 00 00 DW24 : 00 00 00 00 DW25 : 00 00 00 00 DW26 : 00 00 00 00 DW27 : 00 00 00 00 DW28 : 00 00 00 00 DW29 : 00 00 00 00 DW30 : 00 00 00 00 DW31 : 00 00 00 00 Fix it by using phy->mt76->band_idx for queue which works for both non-DBDC and DBDC devices.
