On my arch linux I have:
eth0: 10Gbps
eth1: 2,5Gbps (I suppose it’s the SFP one)
eth2: 1Gbps (WAN POE)
[ 8.997956] mvpp2 f2000000.ethernet eth0: configuring for inband/10gbase-r link mode
[ 9.012377] mvpp2 f2000000.ethernet eth1: configuring for fixed/2500base-x link mode
[ 9.020489] mvpp2 f2000000.ethernet eth1: Link is Up – 2.5Gbps/Full – flow control off
[ 9.054435] mvpp2 f2000000.ethernet eth2: PHY [f212a200.mdio-mii:01] driver [Marvell 88E1510] (irq=POLL)
[ 9.064028] mvpp2 f2000000.ethernet eth2: configuring for phy/rgmii-id link mode
[ 9.072596] mvpp2 f2000000.ethernet eth1: Link is Down
[ 9.079022] mvpp2 f2000000.ethernet eth1: configuring for fixed/2500base-x link mode
[ 9.086889] mvpp2 f2000000.ethernet eth1: Link is Up – 2.5Gbps/Full – flow control off
The 2,5 Gbps is not a real surprise as I already have a machiatobin with the same hardware (mvpp) and there is also a 1Gbps/2,5Gbps port that I use for my fiber access.
