Merge branch 'l2tpeth-info'
Guillaume Nault says:
====================
l2tp: add informations about l2tpeth interfaces in /sys
Patch #1 lets userspace retrieve the naming scheme of an l2tpeth
interface, using /sys/class/net/<iface>/name_assign_type.
Patch #2 adds the DEVTYPE field in /sys/class/net/<iface>/uevent so
that userspace can reliably know if a device is an l2tpeth interface.
====================
