  Modified:    sys/i386/scsi  aic7xxx.c
               sys/pci   aic7870.c
  Log:
  1) SCSI_RESID_VALID was not getting set in xs->flags so even though the
  aic7xxx driver was doing the right thing, it was getting ignored by the
  upper level scsi code.  This may affect tape drives, so I consider this
  a critical fix.
  
  2) xs->status was not set to zero during the initialization of a command.
  Although I don't think this should be the client's (ie the driver's)
  responsibility, it seems that it currently is, so it needs to be cleared.
  Without this change, the upper level scsi code will attempt to interpret
  the sense information on every command complete (since xs->status is
  usually left at 2, "check sense").  This gives a slight performance
  increase, as well as stops fooling /sbin/scsi into thinking there was
  an error on the command.
  
  3) Document that we support the aic7850 controllers in the aic7870.c
  header. Aic7870.c should probably become aic78xx.c sometime down the
  road.
