GMAC's ip_core id is 0x35/0x37, while GNET's ip_core id is 0x37/0x10. Device tables: device type pci_id snps_id channel ls2k1000 gmac 7a03 0x35/0x37 1 ls7a1000 gmac 7a03 0x35/0x37 1 ls2k2000 gnet 7a13 0x10 8 ls7a2000 gnet 7a13 0x37 1 The GMAC device only has a MAC chip inside and needs an external PHY chip; To later distinguish 8-channel gnet devices from single-channel gnet/gmac devices, move rx_queues_to_use loongson_default_data to loongson_dwmac_probe(). Also move mac_interface to loongson_default_data().

The first type shares the same register definitions and has similar logic as dwmac1000. The second type uses several different register definitions, we think it is necessary to distinguish rx and tx, so we split these bits into two. Simply put, we split some single bit fields into double bits fileds: Name Tx Rx DMA_INTR_ENA_NIE = 0x00040000 | 0x00020000; DMA_INTR_ENA_AIE = 0x00010000 | 0x00008000; DMA_STATUS_NIS = 0x00040000 | 0x00020000; DMA_STATUS_AIS = 0x00010000 | 0x00008000; DMA_STATUS_FBI = 0x00002000 | 0x00001000; Therefore, when using, TX and RX must be set at the same time. How to use them: 1. Create the Loongson GNET-specific stmmac_dma_ops.dma_interrupt() stmmac_dma_ops.init_chan() methods in the dwmac-loongson.c driver. Adding all the Loongson-specific macros 2. Create a Loongson GNET-specific platform setup method with the next semantics: + allocate stmmac_dma_ops instance and initialize it with dwmac1000_dma_ops. + override the stmmac_dma_ops.{dma_interrupt, init_chan} with the pointers to the methods defined in 2. + allocate mac_device_info instance and initialize the mac_device_info.dma field with a pointer to the new stmmac_dma_ops instance. + initialize mac_device_info in a way it's done in dwmac1000_setup(). 3. Initialize plat_stmmacenet_data.setup() with the pointer to the method created in 2. GNET features: Speeds: 10/100/1000Mbps DMA-descriptors type: enhanced L3/L4 filters availability: support VLAN hash table filter: support PHY-interface: GMII Remote Wake-up support: support Mac Management Counters (MMC): support Number of additional MAC addresses: 5 MAC Hash-based filter: support Number of ash table size: 256 DMA chennel number: 0x10 device is 8 and 0x37 device is 1 Others: GNET integrates both MAC and PHY chips inside. GNET device: LS2K2000, LS7A2000, the chip connection between the mac and phy of these devices is not normal and requires two rounds of negotiation; LS7A2000 does not support half-duplex and multi-channel; To enable multi-channel on LS2K2000, you need to turn off hardware checksum. **Note**: Currently, only the LS2K2000's synopsys_id is 0x10, while the synopsys_id of other devices are 0x37.
