Device Compatibility Check:
Introduced is_mt7988_eth to determine compatibility with the mediatek,mt7988-eth hardware.
Includes logging messages for debugging compatibility during initialization.
Enhanced MTU Configuration:
Adjusted eth->netdev[id]->max_mtu to support jumbo frames if is_mt7988_eth is true.
Default MTU remains the same for other device types.
Dynamic RX Frame Size Handling:
Modified logic in mtk_mac_config to accommodate jumbo frames and extended frame size configurations:
For MTK_GDM_TYPE, jumbo frames are enabled when is_mt7988_eth is true.
Added logic to handle extended frame sizes for MTK_XGDM_TYPE using the new MTK_XMAC_RX_CFG2.
Initialization Updates:
Extended device initialization to verify compatibility and set is_mt7988_eth accordingly.
Enhanced Register Configuration:
Modified MAC control register (MAC_MCR) handling:
Configures RX frame sizes based on the new maximum frame size (MTK_MAX_RX_LENGTH_9K) if is_mt7988_eth is enabled.
Configures the MTK_XMAC_RX_CFG2 register for MTK_XGDM_TYPE devices.
