[PATCH 25/27] libnetworking: Import current sys/socket.h

Christian Mauderer christian.mauderer at embedded-brains.de
Fri Jun 24 09:38:44 UTC 2016


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

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