From: Kalesh AP <kalesh-anakkur.pura...@broadcom.com>
When the driver receives RESET_NOTIFY async event from FW or detected
an error condition, it should update the application that FW is going
to reset. Once the driver recoveres from the reset, update the reset
recovery status to application as well.
The recovery process is transparent to the application as the driver
itself tries to recover from FW reset or FW error conditions.
