> This patch adds support for firmware recovery mode detection.
>
> The idea behind FW recovery mode is to recover from a bad FW state, due to
> corruption or misconfiguration. The FW triggers recovery mode by setting the
> right bits in the GL_MNG_FWSM register and issuing an EMP reset.
>
> The driver may or may not be loaded when recovery mode is triggered. So on
> module load, the driver first checks if the FW is already in recovery mode. If
> so, it drops into recovery mode as well, where it creates and registers a single
> netdev that only allows a very small set of repair/ diagnostic operations (like
> updating the FW, checking version, etc.) through ethtool.
>
> If recovery mode is triggered when the driver is loaded/operational, the first
> indication of this in the driver is via the EMP reset event.
> As part of processing the reset event, the driver checks the GL_MNG_FWSM
> register to determine if recovery mode was triggered. If so, traffic is stopped,
> peers are closed and the ethtool ops are updated to allow only
> repair/diagnostic operations.
