New Revision: 185855
URL: http://svn.freebsd.org/changeset/base/185855

Log:
  Move flag definitions for t_flags and t_oobflags below the definition of
  struct tcpcb so that the structure definition is a bit more vertically
  compact.  Can't yet fit it on one printed page, though.
  
  MFC after:	pretty soon
