New Revision: 223326
URL: http://svn.freebsd.org/changeset/base/223326
Log:
Fix a KASSERT from r212803 to check the correct length also in case of
IPsec being compiled in and used. Improve reporting by adding the length
fields to the panic message, so that we would have some immediate debugging
hints.
