2bb789d7a3 Add a number of interrelated CAM feature enhancements and bug fixes.
NOTE:  These changes will require recompilation of any userland
applications, like cdrecord, xmcd, etc., that use the CAM passthrough
interface.  A make world is recommended.

camcontrol.[c8]:
 - We now support two new commands, "tags" and "negotiate".

	- The tags commands allows users to view the number of tagged
	  openings for a device as well as a number of other related
	  parameters, and it allows users to set tagged openings for
	  a device.

	- The negotiate command allows users to enable and disable
	  disconnection and tagged queueing, set sync rates, offsets
	  and bus width.  Note that not all of those features are
	  available for all controllers.  Only the adv, ahc, and ncr
	  drivers fully support all of the features at this point.
	  Some cards do not allow the setting of sync rates, offsets and
	  the like, and some of the drivers don't have any facilities to
	  do so.  Some drivers, like the adw driver, only support enabling
	  or disabling sync negotiation, but do not support setting sync
	  rates.

 - new description in the camcontrol man page of how to format a disk
 - cleanup of the camcontrol inquiry command
 - add support in the 'devlist' command for skipping unconfigured devices if
   -v was not specified on the command line.
 - make use of the new base_transfer_speed in the path inquiry CCB.
 - fix CCB bzero cases

cam_xpt.c, cam_sim.[ch], cam_ccb.h:

 - new flags on many CCB function codes to designate whether they're
   non-immediate, use a user-supplied CCB, and can only be passed from
   userland programs via the xpt device.  Use these flags in the transport
   layer and pass driver to categorize CCBs.

 - new flag in the transport layer device matching code for device nodes
   that indicates whether a device is unconfigured

 - bump the CAM version from 0x10 to 0x11

 - Change the CAM ioctls to use the version as their group code, so we can
   force users to recompile code even when the CCB size doesn't change.

 - add + fill in a new value in the path inquiry CCB, base_transfer_speed.
   Remove a corresponding field from the cam_sim structure, and add code to
   every SIM to set this field to the proper value.

 - Fix the set transfer settings code in the transport layer.

scsi_cd.c:

 - make some variables volatile instead of just casting them in various
   places
 - fix a race condition in the changer code
 - attach unless we get a "logical unit not supported" error.  This should
   fix all of the cases where people have devices that return weird errors
   when they don't have media in the drive.

scsi_da.c:

 - attach unless we get a "logical unit not supported" error

scsi_pass.c:

 - for immediate CCBs, just malloc a CCB to send the user request in.  This
   gets rid of the 'held' count problem in camcontrol tags.

scsi_pass.h:

 - change the CAM ioctls to use the CAM version as their group code.

adv driver:

 - Allow changing the sync rate and offset separately.

adw driver

 - Allow changing the sync rate and offset separately.

aha driver:

 - Don't return CAM_REQ_CMP for SET_TRAN_SETTINGS CCBs.

ahc driver:

 - Allow setting offset and sync rate separately

bt driver:

 - Don't return CAM_REQ_CMP for SET_TRAN_SETTINGS CCBs.

NCR driver:

 - Fix the ultra/ultra 2 negotiation bug
 - allow setting both the sync rate and offset separately

Other HBA drivers:
 - Put code in to set the base_transfer_speed field for
   XPT_GET_TRAN_SETTINGS CCBs.

1b69a24904 Only pull 16 bits of residual information from completing queues. This
is a work-around from an LRAM access bug on the 940UA.  In a future
microcode revision, the high 16bits of residual information will be moved
to a safe location and we'll return to 32bit residuals.  Since we only
allow 64KB I/O, 16bits is enough.

queued.

Perform dma segment setup outside of splcam protection as this can take
some time and the protection is not necessary.

808a36ef65 Make the long-awaited change from $Id$ to $FreeBSD$
This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.

Boy, I'm glad we're not using sup anymore.  This update would have been
insane otherwise.

2032d50b04 Advanced Systems Inc. SCSI Controller driver and ISA/VL front end.
I have only tested the ABP5140 card and only with a single CDROM drive
but it seems to work fine.  This driver relies on features found only in
the SCSI branch so will not work in -current until those changes
are brought in.  It also doesn't have any error handling code *yet*.
The goal is to use this driver as the development platform for the new
generic SCSI layer error recovery/handling code.

PCI and EISA front ends will show up as soon as I get my hands on
the cards.  There are also a few issues in the driver that I need
to clear up with AdvanSys before I can suggest sticking one of
these cards in your server. 8-)

Thanks to AdvanSys for releasing this code under a suitable copyright.
