2023-02-02net: ethernet: mtk_eth_soc: disable hardware DSA untagging for second MACArınç ÜNAL
According to my tests on MT7621AT and MT7623NI SoCs, hardware DSA untagging won't work on the second MAC. Therefore, disable this feature when the second MAC of the MT7621 and MT7623 SoCs is being used.

When fail to dma_map_single() in mtk_rx_alloc(), it returns directly. But the memory allocated for local variable data is not freed, and local variabel data has not been attached to ring->data[i] yet, so the memory allocated for local variable data will not be freed outside mtk_rx_alloc() too.

2022-11-18net: ethernet: mtk_eth_soc: implement multi-queue support for per-port queuesFelix Fietkau
When sending traffic to multiple ports with different link speeds, queued packets to one port can drown out tx to other ports. In order to better handle transmission to multiple ports, use the hardware shaper feature to implement weighted fair queueing between ports. Weight and maximum rate are automatically adjusted based on the link speed of the port. The first 3 queues are unrestricted and reserved for non-DSA direct tx on GMAC ports. The following queues are automatically assigned by the MTK DSA tag driver based on the target port number. The PPE offload code configures the queues for offloaded traffic in the same way. This feature is only supported on devices supporting QDMA. All queues still share the same DMA ring and descriptor pool.
