[Michael Tuexen]

Author: tuexen
Date: Tue Oct 11 19:31:02 2011
New Revision: 226268
URL: http://svn.freebsd.org/changeset/base/226268

Log:
  MFC 226203
  
  When moving an stcb to a new inp and we copy over the list of
  bound addresses, update the last used address pointer.
  If not, it might result in a crash if the old inp goes away.
