pine64 512MB network unusable

Hi,

here my iperf and iperf3 stats.

First the tests with the PINE64+, which works, but performs not as expected:


iperf as client running on the PINE64+ against Server on the same switch

The Duplicates are in most cases SACK (selective acknowledgements).

I will try tomorrow to get some stripped tcpdumps, I can post here
