I'm on holiday at the moment, so don't expect fast or full replies.
If ethtool is stating the correct link speed, then it's not a SFP layer
or phylink layer bug.
I don't see any problem with mvpp2 between Armada 8040 hardware running
6.3.0 and 6.1.0 kernels - according to iperf3:
[ ID] Interval Transfer Bitrate Retr
[ 5] 0.00-10.00 sec 1004 MBytes 842 Mbits/sec 46 sender
[ 5] 0.00-10.00 sec 1001 MBytes 839 Mbits/sec receiver
That's mcbin <-(copper)-> Clearfog Base <-(fibre)-> Clearfog gt-8k

FTTP is here! 80Mbps down 10Mbps up. Decent connectivity at last!
