SpacemiT K3: RTL8127 10GbE Controller, but only 1Gbps links?
EDIT:
Phoronix: "The 10 GbE SFP+, Gigabit Ethernet,". And maybe the SFP is fiber-only (not copper, which I try to use)?
/EDIT
"RTL8127 10GbE Controller", but I only get 1 Gbps links ... connected to
- 10GigE router port
- 2.5GigE router port
- 2.5GigE switch port (with very short cable)
My other systems do get 10Gbps resp 2.5Gbps links with the same router/switch/cable.
Do others have more success?
