Kmod-usb-net-rtl8152 on x86

I have problems with download speed with Tp-link U300 usb to 1g lan ? (chip RTL8152). It was working fine until stable 19.07.3, it was able to saturate my 300/300 connection now i have problems with 19.07.4 till 19.07.7 getting only 50Mbs download (upload is fine). Same problem building from master. This is on x86_64 platform. Thanks
