If it doesn't, then what are:

phy_save_paged()
phy_select_page()
phy_restore_page()
phy_read_paged()
phy_write_paged()
phy_modify_paged()

etc?

These are at the _phy_ level because it requires the co-operation of
the PHY driver to select the page in the PHY (each PHY vendor does
paging differently.) They aren't a MDIO bus level thing because paging
doesn't exist at that level.
