Can I check that I've got these things right:

 o *ap is a per sata-HBA-port structure ?
 o each port can have 0, 1 or 2 drives attached ?
   Though 0 & 1 are the only practical values
   for current SATA hardware ?
   Does this become 0 .. n when port expanders
   enter into the picture ?
 o struct scsi_device is a per drive structure ?

So *ap may need to support an aribrary list of devs,
just like struct Scsi_host does today ?

Since I bring up port expanders, will we still get hot-plug
notification from the hardware when a downstream drive changes
state ?
