[KP] The SFP port is connected to Ethernet switch (P9), not to the SoC ports.

[KP] The switch is 88F6393X, which is not yet supported by the current kernel.
The SoC is connected to the switch by eth0 (10G) port.
I just found that "2500base-t" PHY mode used for eth2 is not yet supported by the mainline kernel.
I will disable this port in v2 patches and we will add the appropriate PHY mode support later.
