New Revision: 211115
URL: http://svn.freebsd.org/changeset/base/211115

Log:
  MFp4 CH180235:
  
  Add proto spacers to inet6sw like we have for legacy IP. This allows us
  to dynamically pf_proto_register() for INET6 from modules, needed by
  upcoming CARP changes and SeND.
  MC and SCTP could make use of it as well in theory in the future after
  upcoming VIMAGE vnet teardown work.
  
  Discussed with:	will, anchie
  MFC after:	10 days
