The only fix so far is to change your own board to add the workaround. New chips don't exist yet so no one is getting those until they exist. So everyone is at their own mercy about how long it takes to change the board design and get new boards made, or they can wait for the new chips and hope for the best in the mean time. Doesn't matter if you are Cisco or some tiny company. Of course I suspect Cisco might very well be able to get a new board revision design made a lot faster than the little guys.
