Does Sony include drivers for this chipset ?

https://www.asix.com.tw/products.php?op=pItemdetail&PItemID=131;71;112&PLine=71

USB 3.0 > GbE

If not, can we get included drivers with new android update for XF80 - XF90 series ?

android.hardware.ethernet is presend, but i can't check which drivers are there.

I also don't get it why do all 4k TV sets only have 100Mbit/s network cards, as 4k HEVC movies are mostly 125mbit/s or above.
