+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
