  Log:
  First cut at a driver for the amd53c974 PCI SCSI host adapter.  This
  driver lacks error recovery and still needs more testing, but it's
  about time I got it under revision control.

                         cam_xpt.c 
  Log:
  Add the XPT_PATH_STATS and XPT_GDEV_STATS function codes.  These ccb
  types allow the reporting of error counts and other statistics.  Currently
  we provide information on the last BDR or bus reset as well as active
  transaction inforamtion, but this will be expanded as more information is
  added to aid in error recovery.
  
  Use the 'last reset' information to better handle bus settle delays.
  Peripheral drivers now control whether a bus settle delay occurs and
  for how long.  This allows target mode peripheral drivers to avoid
  having their device queue frozen by the XPT for what shoudl only be
  initiator type behavior.
  
  Don't perform a bus reset if the target device is incapable of performing
  transfer negotiation (e.g. Fiber Channel).
  
  If we don't perform a bus reset but the controller is capable of transfer
  negotiations, force negotiations on the first transaction to go to the
  device.  This ensures that we aren't tripped up by a left over negotiation
  from the prom, BIOS, loader, etc.
  
  Add a default async handler funstion to cam_periph.c to remove duplicated
  code in all initiator type peripheral drivers.
  
  Allow mapping of XPT_CONT_TARGET_IO ccbs from userland.  They are
  itentical to XPT_SCSI_IO ccbs as far as data mapping is concerned.

  scsi_target.c:
  	Release ATIO structures that wind up in the 'unkown command queue'
  	for consumption by our userland counterpart, back to the controller
  	when the exception for that command is cleared.

  Log:
  aic7xxx.c:
  	Honor the 'bus reset at startup' option now that the XPT properly
  	handles transfer negotiation in this scenario.
  
  	Honor the sync rate settings on Ultra2 controllers.  We would
  	always negotiate at the fastest speed.  Oops.
  
  aic7xxx.h:
  	Whitespace.
  
  aic7xxx.seq:
  	Fix a minor nit that would cause the controller to miss the update
  	of the negotiation required bitmask causing the negotiation to
  	be delayed by a command.
