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.

This means drivers can easily get at it and misuse it. Due to the old_ naming this doesn't happen for most of them, but two that have different names have been used wrong a lot (see previous patch). Another downside is that they unessecarily bloat the scsi_cmnd size. This patch moves them onstack in scsi_send_eh_cmnd to fix those two issues aswell as allowing future EH fixes like moving the EH command submissions to use SG lists like everything else.

In particular, these overzealous register writes can cause misdetection problems. Update to do the following once (not once per port) at boot: read 16-bit PCS if needs changing, write 16-bit PCS And thereafter, we only perform a 'read 16-bit PCS' per port. This should eliminate all PCS writes in many cases, and be more friendly in the cases where we do need to enable ports.
