So we need to get a better understanding of that polling. How are you
telling it about the aquantia PHY features? How does it know it needs
to get the current link rate from MDIO_MMD_AN, MDIO_AN_TX_VEND_STATUS1
which is a vendor register, not a standard C45 register? How do you
teach it to decode bits in that register?
