Extremely low RX Rate

[waddisdis]

Kernel 4.19.91

Generally speaking the driver is working but compared to the TX rate I got extremely poor RX rate. With UDP I see a packet loss of about 90%. WiFi sniffer detects dropped packets. I have ruled out hardware and network issues. USB Mass storage TX/RX rates are within parameters as well. CPU is mostly idling Maybe someone here can make sense of this and point me to the right direction.

When receiving data I keep getting these messages:
