svn commit: r230442 - in head/sys: netinet netinet6 netipsec

[Bjoern A. Zeeb]

Author: bz
Date: Sun Jan 22 02:13:19 2012
New Revision: 230442
URL: http://svn.freebsd.org/changeset/base/230442

Log:
  Clean up some #endif comments removing from short sections.  Add #endif
  comments to longer, also refining strange ones.
  
  Properly use #ifdef rather than #if defined() where possible.  Four
  #if defined(PCBGROUP) occurances (netinet and netinet6) were ignored to
  avoid conflicts with eventually upcoming changes for RSS.
