svn commit: r259840 - head/sys/netinet6

[Dimitry Andric]

Author: dim
Date: Tue Dec 24 20:30:13 2013
New Revision: 259840
URL: http://svnweb.freebsd.org/changeset/base/259840

Log:
  In sys/netinet6/in6_mcast.c, in6m_is_ifp_detached() is only used
  whenever KTR is defined, so put it between #ifdef KTR guards.  This
  avoids a warning about a unused function if KTR is not enabled.
