these retransmitts are caused by missing pause-statement in devicetree of bananapi-r2. I got them with mainline driver too.

After fixing it [1], i got the expected results with these mt7531-Patches:

iperf3-client on r2

normal mode:
[ ID] Interval           Transfer     Bitrate         Retr
[  5]   0.00-10.00  sec  1.10 GBytes   943 Mbits/sec    0             sender
[  5]   0.00-10.00  sec  1.10 GBytes   941 Mbits/sec                  receiver

reverse mode:
[ ID] Interval           Transfer     Bitrate         Retr
[  5]   0.00-10.00  sec  1.09 GBytes   939 Mbits/sec    0             sender
[  5]   0.00-10.00  sec  1.09 GBytes   937 Mbits/sec                  receiver
