The network is extremely slow when receiving data, but does the usual 940 Mbit/s full saturation for 1 gigabit when sending. Please see below iperf3 outputs. 10.0.0.201 is my Quartz64 model A and 10.0.0.4 is a pretty powerful amd64 Linux workstation.

Look at all those retransmits! I've verified that the cable and switch port and everything else in the setup are otherwise fine. This happens in both Arch and Plebian. Did I receive a bad board, should I submit an RMA? Or is there something else going on here?
I have similar problem,
I am able to ping other network devices but the 3 quartz64a I own rarelly respond to ping from other devices.
Can you also try pingin the device for a longer time? Sometimes it responds for a minute and then stops for another minute.
