* Altima AC101 PHY registers.
*
* Note the AC101 and the AMD Ac79c874 are the same PHY core. There
* are some registers documented in the AC101 manual that are not in
* the Am79c874 manual, and vice-versa. I have no idea how to tell
* the two apart, but we don't really use the registers that fall into
* this category, anyhow.
