svn commit: r232514 - head/sys/netinet6

[Bjoern A. Zeeb]

Author: bz
Date: Sun Mar  4 18:51:45 2012
New Revision: 232514
URL: http://svn.freebsd.org/changeset/base/232514

Log:
  In nd6_options() ignore the RFC 6106 options completely rather than printing
  them if nd6_debug is enabled as unknown.  Leave a comment about the RFC4191
  option as I am undecided so far.
