Subject: [PATCH net-next v4 05/10] net: airoha: Move qos_sq_bmap in airoha_qdma struct
Date: Thu, 07 May 2026 23:21:48 +0200 [thread overview]
Message-ID: <20260507-airoha-eth-multi-serdes-v4-5-af613b61ae02@kernel.org> (raw)
In-Reply-To: <20260507-airoha-eth-multi-serdes-v4-0-af613b61ae02@kernel.org>
Since now multiple net_devices connected to different QDMA blocks can
share the same GDM port, qos_sq_bmap field can be overwritten with the
configuration obtained from a net_device connected to a different QDMA
block. In order to fix the issue move qos_sq_bmap field from
airoha_gdm_port struct to airoha_qdma one.
