> Fix the current implementation that causes ice_trigger_vf_reset() to start
> resetting the VF even when the VF is still resetting itself and initializing
> adminq. This leads to a series of -53 errors (failed to init adminq) from the
> IAVF.
> 
> Change the state of the vf_state field to be not active when the IAVF asks for
> a reset. To avoid issues caused by the VF being reset too early, make sure to
> wait until receiving the message on the message box to know the exact state
> of the IAVF driver.

> Fixes: c54d209c78b8 ("ice: Wait for VF to be reset/ready before
> configuration")
