svn commit: r184097 - head/sys/netinet

[Bjoern A. Zeeb]

Author: bz
Date: Mon Oct 20 18:56:00 2008
New Revision: 184097
URL: http://svn.freebsd.org/changeset/base/184097

Log:
  Update a comment which to my reading had been misplaced in rev. 1.12
  already (but probably had been way above as the code was there twice)
  and describe what was last changed in rev. 1.199 there (which now is
  in sync with in6_src.c r184096).
