Author: bms Date: Sat Apr 10 12:24:21 2010 New Revision: 206454 URL: http://svn.freebsd.org/changeset/base/206454 Log: When embedding the scope ID in MLDv1 output, check if the scope of the address being embedded is in fact link-local, before attempting to embed it. Note that this operation is a side-effect of trying to avoid recursion on the IN6 scope lock.
