NOT_READY is a sense key, not a legit scsi hostbyte value.
Use DID_NO_CONNECT instead.

For a non-extended REPORT_PHYS, the buffer size is 8, so the divisor needs to be 8.
REPORT_PHYS_EXTENDED has been around a long time, which controller and fw are you testing this on so I can
Also run some tests.

That was seen on an Smart Array 64xx.
Yes, I know, horribly ancient.
But this was sort-of the idea, namely that we can use 'hpsa' as a
complete replacement for cciss.
I'll be fixing up the patch and resubmit it.

Add a sysfs attribute 'ctlr_num' holding the current HPSA controller
number. This is required to construct compability 'cciss' links.
