It's now possible to remove the 'eee-broken-1000t' quirk as > well. I tested this on my Odroid-C1. however, I must admit that I never had issues *without* eee-broken-1000t on any of my boards without your changes: [root@alarm ~]# iperf3 -c 192.168.1.100 Connecting to host 192.168.1.100, port 5201 [ 5] local 192.168.1.194 port 38870 connected to 192.168.1.100 port 5201 [ ID] Interval Transfer Bitrate Retr Cwnd [ 5] 0.00-1.00 sec 80.6 MBytes 675 Mbits/sec 0 2.78 MBytes [ 5] 1.00-2.00 sec 108 MBytes 904 Mbits/sec 0 3.04 MBytes [ 5] 2.00-3.00 sec 106 MBytes 891 Mbits/sec 0 3.04 MBytes [ 5] 3.00-4.00 sec 105 MBytes 880 Mbits/sec 0 3.04 MBytes [ 5] 4.00-5.00 sec 65.0 MBytes 545 Mbits/sec 0 3.04 MBytes [ 5] 5.00-6.00 sec 92.5 MBytes 777 Mbits/sec 0 3.04 MBytes [ 5] 6.00-7.00 sec 72.5 MBytes 608 Mbits/sec 0 3.04 MBytes [ 5] 7.00-8.19 sec 76.2 MBytes 537 Mbits/sec 0 3.04 MBytes [ 5] 8.19-9.00 sec 48.8 MBytes 504 Mbits/sec 0 3.04 MBytes [ 5] 9.00-10.00 sec 87.5 MBytes 736 Mbits/sec 0 3.04 MBytes - - - - - - - - - - - - - - - - - - - - - - - - - [ ID] Interval Transfer Bitrate Retr [ 5] 0.00-10.00 sec 842 MBytes 706 Mbits/sec 0 sender [ 5] 0.00-10.05 sec 839 MBytes 701 Mbits/sec receiver iperf Done.

[root@alarm ~]# RX and TX speeds are within 10Mbit/s before and after the test, so I would call the result "identical" (within a bit of measurement tolerance) I'll wait a few days and see what Emiliano finds out on his board, then I'll send my Tested-by and Acked-by Regards Martin
