Hi thank you for the DSA-driver, works so far, but a bit to improve: i got some retransmitts on RX (TX looks good)...i guess a clk/pll problem Iperf3-Client (BPI-R64,192.168.0.19): root@bpi-r64:~# iperf3 -c 192.168.0.21 Connecting to host 192.168.0.21, port 5201 [ 5] local 192.168.0.19 port 56412 connected to 192.168.0.21 port 5201 [ ID] Interval Transfer Bitrate Retr Cwnd [ 5] 0.00-1.00 sec 114 MBytes 957 Mbits/sec 0 1003 KBytes [ 5] 1.00-2.00 sec 113 MBytes 944 Mbits/sec 0 1.08 MBytes [ 5] 2.00-3.00 sec 112 MBytes 941 Mbits/sec 0 1.08 MBytes [ 5] 3.00-4.00 sec 112 MBytes 941 Mbits/sec 0 1.08 MBytes [ 5] 4.00-5.00 sec 112 MBytes 942 Mbits/sec 0 1.08 MBytes [ 5] 5.00-6.00 sec 112 MBytes 944 Mbits/sec 0 1.21 MBytes [ 5] 6.00-7.00 sec 112 MBytes 944 Mbits/sec 0 1.27 MBytes [ 5] 7.00-8.00 sec 112 MBytes 943 Mbits/sec 0 1.27 MBytes [ 5] 8.00-9.00 sec 111 MBytes 934 Mbits/sec 0 1.27 MBytes [ 5] 9.00-10.00 sec 112 MBytes 944 Mbits/sec 0 1.27 MBytes - - - - - - - - - - - - - - - - - - - - - - - - - [ 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 iperf Done. root@bpi-r64:~# iperf3 -c 192.168.0.21 -R Connecting to host 192.168.0.21, port 5201 Reverse mode, remote host 192.168.0.21 is sending [ 5] local 192.168.0.19 port 56420 connected to 192.168.0.21 port 5201 [ ID] Interval Transfer Bitrate [ 5] 0.00-1.00 sec 112 MBytes 941 Mbits/sec [ 5] 1.00-2.00 sec 112 MBytes 941 Mbits/sec [ 5] 2.00-3.00 sec 111 MBytes 933 Mbits/sec [ 5] 3.00-4.00 sec 112 MBytes 941 Mbits/sec [ 5] 4.00-5.00 sec 112 MBytes 937 Mbits/sec [ 5] 5.00-6.00 sec 112 MBytes 941 Mbits/sec [ 5] 6.00-7.00 sec 111 MBytes 933 Mbits/sec [ 5] 7.00-8.00 sec 112 MBytes 939 Mbits/sec [ 5] 8.00-9.00 sec 112 MBytes 936 Mbits/sec [ 5] 9.00-10.00 sec 112 MBytes 941 Mbits/sec - - - - - - - - - - - - - - - - - - - - - - - - - [ ID] Interval Transfer Bitrate Retr [ 5] 0.00-10.00 sec 1.10 GBytes 942 Mbits/sec 605 sender [ 5] 0.00-10.00 sec 1.09 GBytes 939 Mbits/sec receiver iperf Done.
