    net/ibm/emac: wrong bit is used for STA control register write · 624ca9c3
    Ivan Mikhaylov authored
    STA control register has areas of mode and opcodes for opeations. 18 bit is
    using for mode selection, where 0 is old MIO/MDIO access method and 1 is
    indirect access mode. 19-20 bits are using for setting up read/write
    operation(STA opcodes). In current state 'read' is set into old MIO/MDIO mode
    with 19 bit and write operation is set into 18 bit which is mode selection,
    not a write operation. To correlate write with read we set it into 20 bit.
    All those bit operations are MSB 0 based.
