svn commit: r255739 - in head/sys: cam/ctl dev/iscsi

[Edward Tomasz Napierala]

Author: trasz
Date: Fri Sep 20 21:26:51 2013
New Revision: 255739
URL: http://svnweb.freebsd.org/changeset/base/255739

Log:
  Add some spare fields to structs used by the new iSCSI stack - some just
  in case, some for future MC/S support.
  
  This requires kernel and world rebuild.
