As always, I've hacked MMIO ops to return 0xFFFF for 0x908 PHY reg.
This allowed finding masks used by closed source driver.
At the beginning 0x908 PHY reg ops are following:
phy_read(0x0908) -> 0xffff
phy_write(0x0908) <- 0x0002
(...)
phy_read(0x0908) -> 0xffff
phy_write(0x0908) <- 0x0020
(...)
phy_read(0x0908) -> 0xffff
phy_write(0x0908) <- 0x0200
Later this is always like this:
phy_read(0x0908) -> 0xffff
phy_write(0x0908) <- 0x0000
We do not know the proper condition yet, let's use FIXME for it.
