[PATCH 12/27] libnetworking: Import current netinet6/in6.h

Christian Mauderer christian.mauderer at embedded-brains.de
Fri Jun 24 09:38:31 UTC 2016


From: Christian Mauderer <Christian.Mauderer at embedded-brains.de>

Import the netinet6/in6.h from current FreeBSD. This allows to build
some current software (e.g. libressl).
