Andrew, for this moment with lan743x we can get only this:
sbauer@metamini ~/devel/kernel-works/net-next.git master$ sudo ethtool eth7
Settings for eth7:
Cannot get device settings: No such device
Supports Wake-on: pumbag
Wake-on: d
Current message level: 0x00000137 (311)
drv probe link ifdown ifup tx_queued
Link detected: no
sbauer@metamini ~/devel/kernel-works/net-next.git master$ sudo mii-tool -vv
eth7
Using SIOCGMIIPHY=0x8947
SIOCGMIIPHY on 'eth7' failed: Invalid argument
