Virtual PHY Auto-Negotiation Link Partner Base Page Ability Register (VPHY_AN_LP_BASE_ABILITY)
This read-only register contains the advertised ability of the link partner’s PHY and is used in the Auto-
Negotiation process with the Virtual PHY. Because the Virtual PHY does not physically connect to an
actual link partner, the values in this register are emulated as described below.
