* do not stash pages 2 and 3 (the volume and physdisk pages respectively)dlg2006-07-061-55/+57
| | | | | | | | | | | of the ioc config in the softc. instead, we only walk page 2 when we get the raid config and mark each disks scsi_link structure with the SDEV_LOGICAL flag when we find volumes. while there we mark this instance of the driver as being capable of doing raid so later on we can conditionally hook up bio. when we walk the devices attached to mpi to do ppr, we now skip the logical disks.

| | | | | | | | | either a normal target, or against a physical disk using the raid passthru command. it is necessary since the normal io path can only be used by the midlayer, and only against normal targets. this will be used for ppr against the disks in raid volumes on scsi controllers. tested by marco@

* theres a ton of 32bit fields in mpi messages that have subfields that liedlg2006-06-291-4/+4
| | | | | | | | on byte boundaries. so rather than byteswappping and bitshifting the values in these subfields around we can break them up into byte fields and access them directly. this breaks up the control field in the scsi io command.

| | | | | | | | | | | | we read off the hardware and use to configure the driver with are set to zero, so things dont really work like we want them to. one of these fields is the pci subsystem id which is something we can fetch really early in the attach process. so if the subsys is 0 then we go on and fix up some of the values we get off the "hardware". now we can attach disks on vmware.

* fix sgl loading. there were a few issues, the main ones being:dlg2006-06-121-9/+17
| | | | | | | | | | | - when the sgl grew too large it became bigger than the maximum frame size that the ioc would deal with, and then it would just stop doing io. i was using the wrong field from iocfacts to figure out how large an sgl should be. - chained sgls were broken cos i was including the current chain element in the calculation of the offset to the next chain element. big ok from marco@

* Make id in mpi_complete an unused value instead of random stack garbage.marco2006-06-101-2/+2
| | | | | | This was causing the "empty portfacts" issue since the IOC wasn't complete yet with the request however since the id would match the requested id the timeout was a terminal condition.

* mpi hardware uses an 8 bit field to describe the number of devices it hasdlg2006-05-311-3/+3
| | | | | | | | | on a port. since 256 wont fit into 8 bits they say 0 means 256. this diff does the appropriate interpretation. it also avoids a divide by zero when we figure the openings out by dividing the number of commands the controller can support by the number of devices it supports. panic found while testing the fc controller at home.
