Changelog: Function `phy_mii_ioctl' returns physical device's information based on user requests. When requested to return the basic mode control register information (BMCR), the original implementation only returns the physical device's duplex information and forgets to return speed information, which should not be because BMCR register is used to hold both duplex and speed information.
The patch checks the BMCR value against speed-related flags and fills the return structure's speed field accordingly.
