In fact, would you mind pulling this part out into a separate patch? It
seems like a serious contender to go to stable as it might help with
cards that get into a funny state and don't come back up properly after
a reboot (symptoms are that the adapter wide tlbia / slbia times out and
the driver aborts initialisation).

Cheers,
