New Revision: 228031
URL: http://svn.freebsd.org/changeset/base/228031
Log:
Fix a warning reported by arundel@.
Fix a bug where the parameter length of a supported address types
parameter is set to a wrong value if the kernel is built with
with either INET or INET6, but not both.
MFC after: 3 days.
