V2: do not negate masks
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.
