  Modified files:
    sys/cam/scsi         scsi_da.c 
  Log:
  Automatically detect devices that do not support READ(6)/WRITE(6)
  and upgrade to using 10 byte cdbs.
  
  As far as I tested, this works efficiently for most of the
  SBP-II/Firewire devices but most of the umass devices still need
  ad-hoc work around because umass-sim doesn't return any SCSI errors.
  
  A sysctl nob is also added for the last resort.
  I hope we don't need DA_Q_NO_6_BYTE quirks anymore.
