Subject: [PATCH 1/4] Add support for raw IP interface type
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Under linux some devices can expose raw IP interfaces, such as WWAN
modems. In that case IP data is not encapsulated in any lower level
protocol.

dhclient does not support this currently and this patch adds support
for such pure IP interfaces.

The original patch comes from Bjørn Mork on Network-Manage mailing list:
https://mail.gnome.org/archives/networkmanager-list/2015-December/msg00044.html
