The PHY is capable of 10Mbps communication over long distances and exceeds the IEEE 802.3cg 10BASE-T1L single-pair Ethernet specification. The PHY supports various voltage level signalling and can be forced to support a specific voltage or allowed to perfrom auto negotiation on the voltage level. The default for the PHY is auto negotiation but if the PHY is forced to a specific voltage then the LP must also support the same voltage. Add the 10BASE-T1L linkmodes for ethtool to properly advertise the PHY's capability.
