Subject: [PATCH v2] [net] net: airoha: Fix QoS counter configuration for Tx-fwd channels
Date: Tue, 16 Jun 2026 18:50:29 +0800 [thread overview]
Message-ID: <178161132384.2164449.18407700117859190327@gmail.com> (raw)
In airoha_qdma_init_qos_stats(), the Tx-fwd counter was incorrectly
using register index (i << 1) instead of ((i << 1) + 1). This caused
the Tx-fwd configuration to overwrite the Tx-cpu configuration for
each QoS channel, resulting in incorrect QoS statistics.
Fix by using the correct register index ((i << 1) + 1) for Tx-fwd
counter configuration.
Fixes: 20bf7d07c956 ("net: airoha: Add sched ETS offload support")
