On beaglebone black, it can so happen that PHY address is not latched correctly on reset and board boots with PHY responding to a different address than that programmed in device-tree. For example, see this report:

Workaround this by fixing up device-tree passed to kernel by using the PHY address detected in hardware.
Beaglebone itself uses only one ethernet port and its DT currently uses phy_id (obsoleted). But the function has been written to handle multiple ports and phy_id as well as phy-handle to make the function more generically useful.

Applied to u-boot/master, thanks!
