> From: Masahisa KOJIMA <masahisa.koj...@linaro.org>
> When the interface is down, head/tail of the descriptor
> ring address is set to 0 in netsec_netdev_stop().
> But netsec hardware still keeps the previous descriptor
> ring address, so there is inconsistency between driver
> and hardware after interface is up at a later time.
> To address this inconsistency, add netsec_reset_hardware()
> when the interface is down.
> In addition, to minimize the reset process,
> add flag to decide whether driver loads the netsec microcode.
> Even if driver resets the netsec hardware, netsec microcode
> keeps resident on RAM, so it is ok we only load the microcode
> at initialization.
> This patch is critical for installation over network.
