BTW, for a solution to be complete, we need to halt all work on all
other ports, when issuing SET FEATURES - XFER MODE. On SiI and Promise
controllers, possibly others, the command is snooped and side effects
such as register setting occur.
Long standing to-do. Currently we hack around this by serializing the
bus probe, and preventing people from issuing SET FEATURES - XFER MODE
from userspace.
