    [SCSI] scsi_transport_sas: add unindexed ports · c9fefeb2
    James Bottomley authored
    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.
