    realtek: Fix CRC offloading for rtl83xx
    
    In rtl83xx_set_features we set bit 3 to enable, and bit 4 to disable
    checksuming. Looking at rtl93xx_set_features we however see that for
    both enable and disable the same bit is used (bit 4). This can't be
    right, especially as bit 4 for rtl83xx seems to be Collision threshold
    occupying 2 bits. Change this to make this more logical.
