[SCSI] scsi_transport_sas: add unindexed ports
Some SAS HBAs don't want to go to the trouble of tracking port numbers, so they'd simply like to say "add this port and give it a number". This is especially beneficial from the hotplug point of view, since tracking ports and the available number space can be a real pain. The current implementation uses an incrementing number per expander to add the port on. However, since there can never be more ports than there are phys, a later implementation will try to be more intelligent about this. Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
