NetworkManager/src/devices/nm-device-ethernet.c
Christian Kellner 89af7fbfa6 all: add support for thunderbolt networking 
Load the thunderbolt-net module if we see a host-to-host connection
and configure the resulting ethernet connection automatically to be
a link-local only one. The latter is done by setting a new udev
property "NM_AUTO_DEFAULT_LINK_LOCAL_ONLY" which is picked up when
we configure the connection for the device.
