After hacking MMIO to fool driver's reads:
 phy_read(0x0810) -> 0xffff
phy_write(0x0810) <- 0x0000
 phy_read(0x0810) -> 0xffff
phy_write(0x0810) <- 0x0001
 phy_read(0x0810) -> 0xffff
phy_write(0x0810) <- 0x0000
 phy_read(0x0810) -> 0xffff
phy_write(0x0810) <- 0x0002

So it clearly seems, driver is masking all the bits.
