[PATCH 3/5] device: add new function device_tunnel_get_type()

[Jonatan Schlag <jonatan.schlag@ipfire.org>]

[-- Attachment #1: Type: text/plain, Size: 1215 bytes --]

If we already know that the device must be a ip-tunnel device
we can save time when we check just for the types
a ip-tunnel device can have.

To avoid code duplication we call this function from device_get_type()
