10G_PHY_CAP_23
D34
PHY mode capability pin: Indicates if the PHY
for 10G lanes 2 and 3 is capable of
configuration by I2C. High indicates MDIO-only
configuration, and low indicates configuration
capability via I2C or MDIO. The actual protocol
used for PHY configuration is determined by
the module, in part based on
this input. The actual protocol used is indicated
over the dedicated I2C interface (see Table 13)
