This ethernet device driver for the PCIe interface of Realtek Automotive Ethernet Switch,applicable to RTL9054, RTL9068, RTL9072, RTL9075, RTL9068, RTL9071. v1 -> v2: - Remove redundent debug message. - Modify coding rule. - Remove other function codes not related to netdev. v2 -> v3: - Remove SR-IOV function - We will add the SR-IOV function together when uploading the vf driver in the future. - Remove other unnecessary code and macro. v3 -> v4: - Remove function prototype - Our driver does not use recursion, so we have reordered the code and removed the function prototypes. - Define macro precisely - Improve macro code readability to make the source code cleaner. v4 -> v5: - Modify ethtool function - Remove some unnecessary code. - Don't use inline function - Let the compiler decide. v5 -> v6: - Some old macro definitions have been removed and replaced with the lastest usage. - Replace s32 with int to ensure consistency. - Clearly point out the objects of the service and remove unnecessary struct. v6 -> v7: - Split this driver into multiple patches. - Reorganize this driver code and remove redundant code to make this driver more concise. v7 -> v8: - Add the function to calculate time mitigation and the function to calculate packet number mitigation. Users can use these two functions to calculate the reg value that needs to be set for the mitigation value they want to set. - This device is usually used in automotive embedded systems. The page pool api will use more memory in receiving packets and requires more verification, so we currently do not plan to use it in this patch. v8 -> v9: - Declare functions that are not extern as static functions and increase the size of the character array named name in the rtase_int_vector struct to correct the build warning noticed by the kernel test robot.
