There are several versions of the dp83867 phy supporting various
interface modes.  It seems the driver has been written for the
DP83867IR and DP83867CR family, presumably TI data sheet SNLS484E.
The DP83867E/IS/CS is covered by a separate data sheet, SNLS504B.

Please note that this PHY does not support 2.5G operation in any
mode.
