KSZ9897 DSA Driver for Linux 4.4

[LCHOICEzz]

Hi, recently I want to use KSZ9897 DSA Driver for my Linux 4.4. However, on the github repository, I just find Driver for 4.9. Then I use it for Linux 4.9, it shows some error. So I cannot use it in Linux 4.4.
So, how can I use KSZ9897 DSA Driver for Linux4.4

There is 3.18 driver in linux-drivers/ksz9897/linux-3.18. It is not maintained anymore. Generally the driver only changes for kernel API changes, so you can compare 4.9 and 3.18 drivers and backport the code.
