Hopefully they'll also report here themselves.
I did a quick test on my Q64-A and can confirm it sometime behaves strange when Ethernet has been initialized in U-Boot. At times my iperf3 test report ~0-1 Mbits/sec instead of the more normal ~941 Mbits/sec. After one (or more) "ifconfig eth0 down/up" cycle everything seemed to work okay again. However after one (or more) eth0 down/up cycle the retries was no longer 0 and speed could instead be ~0-1 Mbits/sec. I will see if I can replicate this on other rk3566 boards beside Q64. Can you please try one or more "ifconfig eth0 down/up" cycle and see if that improves your packet loss issue?
