> DM9000 revision B needs 1 ms delay after PHY power-on.
> PHY must be powered on by writing 0 into register DM9000_GPR before
> all other settings will change (see Davicom spec and example code).
> 
> Remember, that register DM9000_GPR was not changed by reset sequence.

> Without this fix the FIFO is out of sync and sends wrong data after
> sequence of "ifconfig ethX down ; ifconfig ethX up".
