New Revision: 269298
URL: http://svnweb.freebsd.org/changeset/base/269298

Log:
  MFC r268808:
  Increase maximal number of SCSI ports in CTL from 32 to 128.
  
  After I gave each iSCSI target its own port, the old limit appeared to be
  not so big.  This change almost proportionally increases per-LUN memory
  use, but it is still three times better then it was before r268807.
