The D-Link driver is for the rtl8822bu, not an rtl8852au. That would make it for 
rtw88, not rtw89. BTW, it will not compile under kernel 5.16.0-rc3, but the 
fixes would be minor.

That driver is the usual collection of junk code published by the Realtek USB 
group for years. That code base is used to generate drivers for Windows, Linux, 
and FreeBSD.

A group is currently modifying the rtl8188eu driver in staging to convert it 
into reasonable Linux shape. This one would take the same effort to make it 
suitable.

The basic USB driver in the neojou repo should work, but I do not have an 
rtl8852au device.
