The MDIO (Management Data Input/Output) protocol decoder supports the
MII Management serial bus (a bidirectional bus between the PHY and the STA),
with a clock line (MDC) and a bi-directional data line (MDIO).

MDIO is also known as SMI (Serial Management Interface).

It's part of the Ethernet standard.
