[net-next,v2,0/3] DP83TD510 Single Pair 10Mbps Ethernet PHY

Hello

The DP83TD510 is an Ethernet PHY supporting single pair of twisted wires. 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.
