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 cm#pš x
